Frequencyoffsets in the receivea signal can degrade the performance of trequency hopping, multiuser spread spectrum communication systems that use ki-AryFSK modulation. To compensate for this degradation a windowed receiver is used which will allow suppression of adjacent clhannel interference. It is then necessary to find out how the system performance will change withi the variation of window parameters. We present a technique for estimating the symbol error rate for windowed M-Ary reception. Optimum window parameters are found for M-Ary FSK for M = 2, 4 and d. t The researchlreported herein was supported under a research contract from the Canadian Departments of Communications and National Defence.
