Abstract

The power spectral density (PSD) of a modulated signal is a direct indication of the bandwidth efficiency of the modulation scheme. A modulated signal with wider PSD consumes more transmission bandwidth compared to a signal that has narrower PSD. This research will provide expression for high power spectral density without increasing in the transmission bandwidth by using of M-ary PSK signals, which can be specialized for M _ 2 (BPSK) , M _ 4(QPSK) ,M-8(OPSK) and M-16. To simplify things, it use the fact that for pass band signals with certain properties. the performance of M-ary PSK modulation will be introduced with a generated noise , in additive white Gaussian noise channel(AWGN) :and compare between the performance of the types above .
