Abstract :
In this paper, we present a phase synchronization algorithm which exploits the data redundancy brought by a single parity-check code. The symbol decoding of a parity equation is discussed first. Then, a soft detection directed (SDD) estimation technique is derived for any modulation scheme. The performance of the developed SDD phase estimator is evaluated with 8PSK modulation in very low SNR condition. It appears to greatly outperform the non data aided Viterbi and Viterbi estimator. Quite robust to phase noise, it seems well suited to the context of satellite burst transmissions
