Abstract :
Frequency offsets in the receivea signal can degrade the performance of trequency hopping, multiuser spread spectrum communication systems that use M-Ary FSK modulation. To compensate for this degradation a windowed receiver is used which will allow suppression of adjacent channel interference. It is then necessary to find out how the system performance will change with 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 8.
