Hello all!

I wanna make sure the way to calculate the transmission bandwidth for

USRP system. As we know, the bitrate could be obtained based on

bitrate=128/m/k, where m is the interpolation rate and k is the samples

per symbol(suppose we use bpsk modulation), once we get bitrate, how to

get the bandwidth? Should we have to use bitrate to divide spectral

efficiency(R/W) to get bandwidth? If it is bpsk modulated, R/W is 1 and

bandwidth is equal to bitrate? I think some kind of ideal filtering has

been used in this case, but what is the actual bandwidth in the real

world???

Thanks for everyone!

Bill
