Abstract

A low complexity carrier phase estimation (CPE) algorithm for 16-QAM systems is investigated in this paper. In the proposed CPE algorithm, the QPSK partitioning scheme is adopted to divide the symbols into three classes (C1, C2 and C3). The symbols in C1 and C3 are used to achieve the coarse estimation and then the symbols in C2 are used to achieve the fine estimation. In addition, the Mth-power operation is replaced by the M-level absolute operation for the removal of modulated data phase, which greatly reduced the complexity. The simulation results show that the proposed algorithm has better linewidth tolerance that the traditional Viterbi and Viterbi (V&V) algorithm.
