Abstract :
An estimator that is based on maximum likelihood approach for joint detection and synchronization is presented. The structure consists of a fractionally spaced feedforward filter for equalizing the channel distortion, a demodulator and a maximum likelihood estimator incorporated with decision feedback for determining the demodulator´s phase angle and the transmitted symbols. Different tracking algorithms at the symbol rate are discussed and their performances are compared by computer simulations
