I know that in a RRC filter a high value of the span gives a better response, in the sense that the RRC filter response is more near to the ideal RRC filter response. However, would there be any advantage on using a small span?
Lets say, for example, that I am sending
100 BPSK symbols, a value of
span = 10, would be better, in terms of the BER, than a
span = 2.
Q: But would there be any advantage with
