Performance of MPSK signal predetection EGC diversity receiver

In this paper a performance analysis of modified M-ary phase-shift-keying (MPSK) signal diversity receiver with predetection equal gain combiner (EGC) will be presented. The modification is in introducing a structure that performs the estimation with remodulation (ER). The EGC combining is realized by using the constant modulus algorithm (CMA). The influence of carrier frequency offset, length of ER structure and other parameters of the receiver will be examined.
