How ISI can be removed by employing a raised cosine filter?

Employ raised cosine filtering to reduce inter-symbol interference (ISI) that results from a nonlinear amplifier. Initialize a simulation variable for modulation order. Create square root raised cosine filter objects.

How raised cosine filter is used in pulse shaping to minimize ISI?

Square-Root Raised Cosine Filters

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.

Why use root raised cosine?

Using 90% power Bandwidth (BW) measurement definition showed that the RRC filtering might improve spectrum efficiency by more than 75%. Furthermore using the matching RRC filters both in the transmitter and receiver provides the improved Bit Error Rate (BER) performance.

Which of the statements are the limitations of the raised cosine filters?

Raised cosine filter does not satisfy Nyquist criteria.
