| Summary: | acquisition and are simple and practical to implement. acquisition for QAM constellations, and specifically for algorithm and the performance is improved, but not enough algorithm is developed which reduces the complexity of the be simpler but still impractical. The power-law (PL) but impractical to implement. A suboptimal ML type constellations which further improves performance, but developed. Finally a suboptimal version of the trellis error performance. A threshold is added to the PL estimator is derived as the low SNR limit of the ML estimator is derived from the ML algorithm and is found to estimator, and is found to be very simple, but having poor for rapid phase acquisition for most cases. An algorithm in all are derived and tested. The first is the maximum- is derived specifically for use on the cross is no frequency or symbol timing error. Seven algorithms likelihood (ML) estimator, which is found to be accurate operating over an AWGN channel. It is assumed that there suboptimal trellis algorithm perform well enough for phase the 32-QAM, 64-QAM, 128-QAM, and 256-QAM constellations, this algorithm is superseded by an estimator based on a This work addresses the problem of rapid carrier-phase trellis algorithm by two-thirds. Both the trellis and the trellis structure and the Viterbi Algorithm which is |
