Abstract :
This paper examines the joint synchronization and detection of Ungerboeck coded modulation. Estimation theory is used to derive a synchronization structure that is efficient in estimating carrier phase and symbol timing. The maximum likelihood receiver generates estimates of carrier phase and timing that are free of data-dependent jitter for any continuous pulse shape. Various feedback schemes to be used with Ungerboeck codes are presented and simulated. Simulations show that efficient estimates of carrier and clock can be found when joint data and parameter estimation of an Ungerboeck coded signal is performed
