Raised Cosine Filtering - MATLAB & Simulink - MathWorks Italia
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. The Raised Cosine Receive Filter block's icon ... WebbThe 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: athena karkanis kinder
