Joint Carrier Phase Estimation and Turbo Decoding Using Bit Carrier Phase APP Decoder [PDF]
In this paper, we present an algorithm for joint carrier phase estimation and turbo decoding for the case of rapidly varying carrier phase during the transmitted block. The proposed algorithm shows improved performance over previously proposed communication schemes, both coherent and noncoherent, for channels with additive white Gaussian noise and high
