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. WebbPulse Shaping Using a Raised Cosine Filter.

WebbWe will create a raised-cosine filter using a of 0.35, and we will make it 101 taps long to give the signal enough time to decay to zero. While the raised cosine equation asks for our symbol period and a time vector , we can assume a sample period of 1 second to “normalize” our simulation. WebbRaised cosine filters are used for pulse shaping, where the signal is upsampled. Therefore, we also need to specify the upsampling factor. The following is a list of parameters used to design the raised cosine filter for this example. Nsym = 6; % Filter span in symbol durations beta = 0.5; % Roll-off factor sampsPerSym = 8; % Upsampling factor britney allen bring it on: all or nothing
