@article{Some1997EfficientEO, title={Efficient estimation of continuous phase modulation with unknown carrier phase}, author={Y. K. Some and P. Y. Kam}, journal={IEEE Trans. Commun.}, year={1997}, volume={45}, pages={765-767} }

An efficient algorithm is presented for the estimation of continuous phase modulation (CPM) sequences over the Gaussian channel with unknown carrier phase. It operates on the excess phase trellis like the Viterbi algorithm, except that it is not a maximum-likelihood (ML) estimator. Its decision metric for survivor selection at each node is chosen so that it achieves the node error event probability of coherent ML estimation in the limit as the carrier phase remains constant over a long intervalâ€¦Â CONTINUE READING
