Özet

This paper investigates practical implementations of a maximum likelihood sequence estimator (MLSE) receiver for CPM based on Laurent decomposition using Viterbi algorithm. On the other hand, the decomposition of the CPM signal in the Walsh signal space that brings the less hardware requirement is investigated. For both of the receiver structure, some suboptimal versions are proposed to reduce the receiver complexity and the performance comparison is done for additive white Gaussian noise channels via MATLAB simulation.
