摘要： An adaptive receiver to provide reliable estimates of the symbols for the high-order MQAM and MPSK modulated signals received in the presence of amplitude fading and phase dynamics induced due to time-varying atmospheric or terrestrial multipath fading encountered in wireless communication channels. The adaptive receiver encompasses an adaptive tracking loop comprised of adaptive channel fade envelope estimator derived from the high-order modulated signal, a novel phase detector to separately estimate the phase due to the fading channel and the reference oscillator from that due to the data modulation present in the received signal without the need of any pilot symbol or pilot carrier, and a Kalman filter, a fixed-lag smoother and a smoothed symbol detector.
