Describes general comm filtering.
- Group Delay
The raised cosine filter blocks in the
commfilt2library implement realizable filters by delaying the peak response.
- Design Raised Cosine Filters Using MATLAB Functions
Designing a raised cosine filter using the
- 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.
