Coded continuous phase modulation with low-complexity noncoherent reception

Coded continuous phase modulation based on a feedback–free modulator with noncoherent detection is discussed. Low–complexity receiver processing is achieved by using only two or three linear filters for demodulation and applying noncoherent sequence estimation with reduced–state Viterbi decoding and simple branch metric calculation. Overall, the proposed noncoherent receiver provides significant advantages over recently presented approaches. The material in this letter will be presented in part at the IEEE International Conference on Communications (ICC), Helsinki, June 11-15 2001.
