3 measurements taken within a single day, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 694–695 and does not start at zero.

ERR is average views per post over the last 30 days divided by subscribers, the definition TGStat uses, so this figure is comparable with the one you will see elsewhere. It falls structurally as a channel grows: a high ERR on a small channel and a low one on a large channel describe reach mathematics, not quality. We publish the figure and the sample it came from and pass no verdict on it.
ER is defined industry-wide as (forwards + reactions + comments) ÷ views— note the denominator is views, not subscribers. Telegram’s public web preview carries views and reactions but not forward or comment counts, so the reaction rate above is the reactions term only and is therefore a floor: the true ER for this channel is higher by an amount we have not measured and will not estimate.

Views are a single reading per post, taken at the time above. A post published in the last day or two is still accumulating views, which pulls the 30-day average down slightly. That is a property of the standard definition rather than a fault in it, so we keep the definition rather than “correcting” the number into something nobody can reproduce.
Precision. Telegram publishes view counts on its public widget in short form — 8.12K, 3.7M — so any reading at or above 1,000 reaches us rounded to three significant figures, and only counts below 1,000 are exact. Averages and rates derived from them are shown to the same precision rather than to the unit: a figure like 3,701,250 would assert digits nobody measured.
Reaction counts are published per emoji and rounded the same way, so a total below 1,000 is exact and a larger one is a sum that may carry a rounded component from each emoji above 1,000. Because it is a sum, it does not look rounded — read a large reaction total as three significant figures per contributing emoji rather than as the figure it prints.
Reaction mix
94 reactions across 18 posts, in 6 distinct kinds. The most used accounts for 44.7% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 18 of the 19 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 94reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 19 most recent posts we hold, published 5 July 2026 to 3 August 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

در این قسمت به موضوع تکنیک مدولاسیون direct sequence spread spectrum پرداختهایم. در جلسات گذشته این تکنیک را به صورت غیر استاندارد به صورت عملی پیادهسازی کردهایم. تقریبا مانند الگوریتم دریافت داده در GPS.
ولی در این قسمت و در قسمتهای اینده قصد داریم این تکنیک را به صورت استاندارد پیادهسازی کنیم.
در این قسمت ابتدا از شبیهسازی شروع کردهایم و بعد از این که فرستنده پیادهسازی شد به…

اما امروز داشتم با دقت به موضوع Direct sequence spread spectrum توجه میکردم بعد از این افست فرکانسی درشت تخمین زده شد، صد در صد ما یک خطا داریم .
من رفتم و بیت اولم رو despread کردم اما با چنین صحنه ای روبه رو شدم یعنی شکل بالا به جای شکل پایین.
اما قبلا این رو میدونستم که #هرچهزمانبگذرهاینCFOباقیماندهرویهمجمعمیشوند و این جا دقیقا به چشم دیدم تجمع این خطاها رو. و این تجمع خطا…

یکی از دوستان به همراه دوستان دیگرش طراحی برد sdr انجام میدهند.
و این بردشون oneSDR است و این که دو فرستنده و دو گیرنده داره و پهنای باند گیرنده ها 200 مگاهرتز و پهنای باند فرستنده ها 450 مگاهرتز.
بقیه ویژگی ها داخل کاتالوگ اومده.

در ادامه جلسات مخابرات دیجیتال در gnu radio به موضوع pulse shaping پرداخته شده است pulse shaping مورد استفاده square root raised cosine میباشد و سپس نحوه به دست آوردن پهنای باند آن.
در ادامه تیز مقایسهای بین pulse مستطیلی و square root raised cosine شده است.

در این کد به صورت خیلی ساده به موضوع #گیرندهGPS پرداخته است این کد به نظرم خیلی جالبه چون خودم هم مقداری خوندمش.
نکته مهم این است که حتما نباید از داده های GPS استفاده کنید میتونیم از این کد برای گیرنده DSSS استفاده کنیم. و برای فهم گیرنده DS به شدت توصیه میشود.

سلام وقت همگی بخیر بعد از مدتها وقفه دوباره اومدیم.
در این سری از قسمتها به موضوع مدولاسیونها دیجیتال و پیادهسازی فرستنده و گیرنده مخابراتی به صورت real time میپردازیم.
در این قسمت به constellation مدولاسیونهای BPSK و QPSK پرداخته شده است.
ببخشید این قسمت صدا مقداری ضعیف میباشد.

یکی از دوستان گفت این رو در کانال قرار بدهم و میتونند usrp هم وارد کنند.
یکی از شرکتها یک USRP B210 Original داره که بسیار کم کار کرده و میخواهند آن را بفروشند. این usrp دارای ویژگیها و تجهیزات جانبی زیر است:
همراه با کابل USB3
فرکانس کاری آن 70 مگاهرتز و محدود فرکانسی آن تا 6 گیگاهرتز است
آموزش رایگان هم میدن در محیط GNU radio همراه تست و دیباگ.

Showing the 12 most recent of 19 posts we hold for @SDR_two. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Citation-graph rank
Citation-graph rank — 233,528 of 1,169,250entries in the measured graph. A weighted position computed from the forward and mention edges below — republished posts weigh more than named mentions — and recomputed periodically, over the whole graph. Published only as this ordinal position, never as a score: a position is a fact, and a score printed beside one channel’s name would read as a verdict this register does not make. The two counts beneath stay separate for the same reason mentions are never summed with forwards anywhere else on this page — a named-by count costs nothing to manufacture. The top 100 by this measure, or how it is computed.
Forward network
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Named by 2 registered channels — every channel on the register whose own posts have named this one, by its current username or any other username it currently holds, merged from two separately captured readings of the same fact so a namer caught by only one of them is not missed and a namer both caught is not counted twice. A username this channel has since dropped is not matched — that handle may belong to someone else now, and crediting today’s namer to yesterday’s owner would misattribute it.
Named by
Channels on the register whose posts name this channel's handle.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.

@SDR_two named 1 handle that resolve to nothing today. That is a fact about the reference, not necessarily a fact about the handle’s history — see the two groups below.
Most of these may never have existed as a live channel at all.A handle a channel names can be a typo, an aspirational name nobody registered, or a channel that was already gone before this one ever mentioned it. Unless a row below is marked evidenced, all we know is that it references a handle that is not a live channel today — not that anything “died”. How this is measured.
Never seen alive
References a handle that is not a live channel — we have no record it ever was one.
