Abstract

Pilot symbol assisted modulation (PSAM) is a method to reduce the effects of fading in mobile communications by periodically inserting known symbols in the data stream. The receiver uses these pilot symbols to derive its amplitude and phase reference. In this paper, standard maximum likelihood (ML) estimation techniques are used to derive optimum synchronization structures for AWGN and slow Rayleigh fading
