Joint Carrier Phase Estimation and Turbo Decoding Using Bit Carrier Phase APP Decoder [PDF]
IEEE Transactions on Communications, 2007 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

Carrier phase synchronizers [PDF]
, 2018 This work studies four carrier phase synchronizers (CPS) or carrier Phase Lock Loop (CPLL). The synchronizers are based in a loop with VCO (Voltage Controlled Oscillator) that synchronizes the output feedback with the input.

Integrity Monitoring for Carrier Phase Ambiguities [PDF]
Journal of Navigation, 2011 The determination of the correct integer number of carrier cycles (integer ambiguity) is the key to high accuracy positioning with carrier phase measurements from Global Navigation Satellite Systems (GNSS). There are a number of current methods for resolving ambiguities including the Least-squares AMBiguity Decorrelation Adjustment (LAMBDA) method ...

A Refinement to the Viterbi-Viterbi Carrier Phase Estimator and an Extension to the Case With a Wiener Carrier Phase Process [PDF]
IEEE Access, 2019 We provide a theoretical foundation for further analysis and optimization of the Mth-power (MP) carrier phase estimator for MPSK modulation. Also known as the Viterbi-Viterbi (VV) estimator, it is commonly used in practice because it leads to low-latency receiver implementations.

Homodyne coherent detection of ASK and PSK signals performed by a subcarrier optical phase-locked loop [PDF]
, 2005 Optical transmission systems based on homodyne coherent detection of 2-ASK and pilot carrier 2-PSK signals have been implemented. ASK data has been transmitted at 2.5 Gbps, while 2.5 Gbps and 10 Gbps PSK systems have been tested.
