Abstract

In this paper, the application of artificial neural network (ANN) to differential detection receiver for M-ary differential encoded phase-shift keying (MDPSK) utilizing multiple symbols is investigated. It is shown that the performance of this non-coherent receiver not only approaches its coherent receiver counterpart, but its structure is also simple and easy to implement in hardware. Some other desirable properties are obtained, such as no training process involved in this application, fast computational time and high accuracy. Simulation results are made to illustrate its superior performance
