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.

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.

What is a raised cosine spectrum?

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.

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.
