WebbThe Raised Cosine Receive Filter block filters the input signal using a normal raised cosine FIR filter or a square root raised cosine FIR filter. It also downsamples the filtered signal if you set the Output mode parameter to Downsampling . The FIR Decimation block implements this functionality.

Webb1 maj 2008 · Matlab/Octave script for simulating the eye diagram plot. The code performs the following (a) Defines random BPSK modulated symbols (+1’s and -1’s) (b) Defines two raised cosine filters with = 0.5, = 1 (c) Upsamples the transmit sequence by zero insertion (d) Convolves the upsampled transmit sequence with the filter WebbCreate a normal raised cosine filter with rolloff 0.25. Specify that this filter span 4 symbols with 3 samples per symbol. rf = 0.25; span = 4; sps = 3; h1 = rcosdesign (rf,span,sps, "normal" ); impz (h1) The normal filter has zero crossings at integer multiples of sps. It thus satisfies Nyquist's criterion for zero intersymbol interference.
