Honored ContributorRRC Matched Filter Design
Hi, I have implemented an RRC filter in the transmitter side, and according to texts and articles I read, the matched filter in the receiver side is the same as in the transmitter. Later, I...

Honored Contributorgreat you have reached the receiver now.
The receiver rrc filter has to be same as transmitter. Though the number of taps, sampling rate or any interpolation/decimation may be different from that of Tx filter. The idea is both filtering of noise as well as doing correlation to maximise snr. The correlation part requires reversal of coefficients in principle. But as long as the filter is symmetrical then you are free to reverse it and see what you get !! since I haven't heard of anyone designing asymmetric rrc coeffs I better not swear at those unpractical dsp writers who also keep talking about infinity and minus infinity things.
