Abstract

A subspace-based algorithm to estimate carrier phase for PSK modulation is described. The performance of the algorithm is close to the optimum maximum-likelihood estimate. The approach is blind and based on a subspace decomposition of the received data. Comparisons of our proposed approach are made with other techniques available in literature. The performance of the algorithm with respect to the Cramer-Rao lower bound (CRLB) for the estimation of the carrier phase is investigated. Computer simulation results for BPSK, 4PSK and 8PSK are presented.
