AbstractA general vector digital signalling scheme for data communication through an additive Gaussian channel is made adaptive for the purpose of simultaneous communication of information and phase estimation. The phase estimate is shown to converge to the true value, therefore the adaptive nature of the detector effectively achieves phase acquisition and improvement in performance. Qualitative comparison to other phase acquisition techniques is made. The basic virtues of the proposed method are that no separate synchronization interval is required, and phase fluctuations can be tracked simultaneously with the transmission of information.
