What is raised cosine function?

A typical use of raised cosine filtering is to split the filtering between transmitter and receiver. Both transmitter and receiver employ square-root raised cosine filters. The combination of transmitter and receiver filters is a raised cosine filter, which results in minimum ISI.

How to use Rcosdesign in Matlab?

Generate the coefficients of the square-root raised cosine filter using the rcosdesign function. rrcFilter = rcosdesign(rolloff,span,sps); Generate 10000 data symbols using the randi function. data = randi([0 M-1],10000,1);

What is raised cosine spectrum in digital communication?

The raised-cosine filter is a filter frequently used for pulse-shaping in digital modulation due to its ability to minimise intersymbol interference (ISI). Its name stems from the fact that the non-zero portion of the frequency spectrum of its simplest form ( ) is a cosine function, 'raised' up to sit above the.
