Signal Reciever

A very easy symbolic method for reduction of block diagrams or signal flow graphs with Matlab is presented. The method can be applied to every kind of diagram and it is possible to obtain in one stage all transfer functions for a given input. The method is validated with some examples, including...

%DVBS2Constellation Signal Constellations taken from ETSI EN 302 307% [CONSTELLATION, BITMAPPING] = DVBS2Constellation(MODSCHEME,GAMMA)% returns the constellation points and the bit mapping specified in the DVB-S2% Standard ETSI EN 302 307. The output vector CONSTELLATION contains the%...

Tapers start and end samples of a given signal for a fade-in and fade-out effect. Fade-in and fade-out durations can be independently controlled. Custom tapering window can be specified also.
