The main objective is to compare and the carrier. One phase represents the logic 1, and the other identify which modulation is better by analyzing the phases represent the logic 0. It does not particularly matter performance of both channels in CDMA environment. This paper modulation is the most robust of all the PSKs since it takes provides analysis, evaluation and computer simulations in serious distortion to make the demodulator reach an incorrect MATLAB decision.

With more than 8 phases, the error-rate becomes too high and there are better, though more complex, I. Although any number of A llowing several transmitters to send information simultaneously over a single communication channel is phases may be used, the fact that the constellation must usually deal with binary data means that the number of one of the basic concepts in data communication [1].

This symbols is usually a power of 2 — this allows an equal means, it allows several users to share a bandwidth of number of bits-per-symbol [4]. This concept is called multiplexing technique. The incoming bits where each transmitter is assigned a code to allow multiple are mapped to eight possible symbols phases by users to be multiplexed over the same physical channel.
