Yes there will be a difference, the RRC filter block is just a wrapper for a call to firdes to design an RRC with the specified sampling rate/symbol rate/excess bandwidth/ntap. The designed taps are then used in a fir filter block whose decimation or interpolation is determined by the field you pro

RRC filter understanding

2021-05-29 Thread Ivan Penchev Ivanov
Having a background with Matlab, now I am working on QPSK transceiver in Gnuradio. I have a question for understanding RRC filter parameters in Gnuradio. Let's take an RRC interpolation filter in the transmitter. There are parameters for sample rate and for symbol rate. Suppose my sample rate is 32
