Initially, we used BPSK for a certain transmission. However, we then found that the bandwidth of BPSK is too wide for our channel. If we are willing to reduce distance, d, by a factor of no more than 25, what is the minimum bandwidth we can have if we were to use M-PSK under these constraints? Note that in order to answer you need to find M = 2 N. Submit all your written work by tomorrow 8 AM on Canvas.
