Signals Analysis: SA update to version v 6.2.6.5

http://signals-analysis.blogspot.com/2012/01/sa-update-to-version-v-6265.html

Среда, 25 января 2012 г. SA update to version v 6.2.6.5. SA update to version v 6.2.6.5. In this update, possibility of resample and shift of the signals on fractional values of frequencies is added. Perhaps more important part of current updating, is the first stage of integration in SA calculator K. Nevertheless, even in such, very strongly simplified kind, it is already possible to receive authentic enough values K on some signals. English Version of our official site. Demo version, updates, online he...

Signals Analysis: New article: "GMSK and OQPSK"

http://signals-analysis.blogspot.com/2011/11/new-article-gmsk-and-oqpsk_707.html

Суббота, 19 ноября 2011 г. New article: "GMSK and OQPSK". It's a small article. Which dealt with the problem of identifying GMSK and OQPSK. We hope this will be useful. It's a small fragment. OQPSK and GMSK are tightly connected, as well as SDPSK and CPFSK, as well as pi/4 DQPSK and C4FM. Such "dualism" is spread enough, and connected/linked by the fact that often some modes of frequency shift keying at some conditions, smoothly flowing and/or aspire to acquire the shape of phase manipulation. Then the s...

The analogue dynamical synchronized scramler. It sounds like "Pinocchio" :-). The features of this signal: the preamble is the same as two-channeles FSK-2 with the parameters ( look pic.1). There are short synchro-bursts also every 400 ms (look pic.1). Ссылки на это сообщение. Подписаться на: Сообщения (Atom). FSK, GFSK, MSK, ...
