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.

WebbRaised-Cosine (RC) and Root-Raised-Cosine (RRC) filters are commonly used in digital data modems. Here, we provide design formulas for these filters. Notes: Each version of the same formula is algebraically equivalent; they just use different parameters. The impulse response formulas include a “sinc(x)” term, that is, “sin(x)/x”. Webb3 maj 2016 · Let’s look at a somewhat more realistic textbook signal: The PSK/QAM signal with independent and identically distributed symbols (IID) and a square-root raised-cosine (SRRC) pulse function. The SRRC pulse is used in many practical systems and in many theoretical and simulation studies. introduction to cgWebbA typical use of raised cosine filtering is to split the filtering between transmitter and receiver.

WebbI can control the roll-off factor, $\beta$, of the root-raise cosine filter. What are the practical implications of this number? It seems that any value should work fine, since it fulfills the nyquist criteria (adjacent symbols have zero energy at the current symbol's sample point) and the energy/frequency is constrained.
