Webb18 juli 2016 · For $\alpha = 0$, there is no difference between a Raised Cosine and a Square-Root Raised Cosine filter due to a rectangular spectrum. Also notice from Eq \eqref{eqCommSystemSR-RaisedCosineFreq} that the transition band of a Square-Root Raised Cosine pulse is a quarter cycle of a cosine as compared to a half-cosine of a … WebbThis upsampled pulse stream is then filtered through a root-raised-cosine pulse-shaping filter, which is a finite impulse response filter (FIR) with a predefined shape. This particular filter is 3 symbols wide. At 16 samples per symbol, the filter contains 49 taps in total (3 x 16 taps + 1 center tap).

"The raised-cosine filter is an implementation of a low-pass Nyquist filter, i.e., one that has the property of vestigial symmetry. This means that its spectrum exhibits odd symmetry about , where is the symbol-period of the communications system. Its frequency-domain description is a piecewise-defined function, given by: " - Theory of root-raised cosine filter
