What is a raised cosine pulse?

The raised cosine pulse is one type of Nyquist-II pulse. It possesses a transfer function given by. (3.67) where β is called the roll-off factor, which takes values between 0 to 1, and β/2T is called the excess bandwidth. Figure 3.23 illustrates the raised cosine spectral characteristics.

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 square root raised cosine?

In signal processing, a root-raised-cosine filter (RRC), sometimes known as square-root-raised-cosine filter (SRRC), is frequently used as the transmit and receive filter in a digital communication system to perform matched filtering. This helps in minimizing intersymbol interference (ISI).

Which are the advantages of the raised cosine pulse shape?

It allows for a transmit filter to limit channel bandwidth then inserts a receive filter to attenuate out-of-band channel noise.
