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). The combined response … Visa mer To have minimum ISI (Intersymbol interference), the overall response of transmit filter, channel response and receive filter has to satisfy Nyquist ISI criterion. The raised-cosine filter is the most popular filter … Visa mer The RRC filter is characterised by two values; β, the roll-off factor, and Ts the reciprocal of the symbol-rate. The impulse response of such a filter can be given as : Visa mer WebbThe good thing about the square-root raised cosine pulse shape is that the corresponding matched ﬁlter output has no ISI. The bad thing is that the pulse shape has inﬁnite support in time. In a practical system, pulses cannot last indeﬁnitely. So …
