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 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.
What is SRRC in communication?
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.
