Abstract :
We consider the error performance of frequency dehopped, noncoherent, M-ary FSK when the receiver is a bank of energy detectors. The effects of phase noise and frequency offset are included in the analysis as our application is for the EHF band with fast-frequency hopping. Our result on the effect of frequency offsets on the bit error rate (BER) is the most complete and reduces to a well-known formula due to Stein. This result is used to study the performance of a windowed receiver in a multi-user Binary FSK environment. Receiver windowing is a form of mismatch in order to reject adjacent channel interference. We show when it is useful and how to optimize receiver performance when windowing is utilized.
