Raised cosine filter matlab code
WebbGenerate the coefficients of the square-root raised cosine filter using the rcosdesign function. rrcFilter = rcosdesign (rolloff, span, sps); Generate 10000 data symbols using the randi function. data = randi ( [0 M-1], 10000, 1); Apply PSK modulation to the data symbols. 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.

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 WebbDesign Raised Cosine Filters in Simulink This example illustrates a typical setup in which a transmitter uses a square root raised cosine filter to perform pulse shaping and the …
