Filtering
Describes general comm filtering.
Group Delay
The raised cosine filter blocks in the commfilt2 library implement realizable filters by delaying the peak response.
Design Raised Cosine Filters Using MATLAB Functions
Designing a raised cosine filter using the rcosdesign function.
Design 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 corresponding receiver uses a square root raised cosine filter as a matched filter.
