一种适用于BPSK和QPSK的非数据辅助前馈符号定时估计器
Non-Data-Aided Feedforward Symbol Timing Estimator for BPSK and QPSK
提出一种适用于二进制相移键控(BPSK)和四进制相移键控(QPSK)调制方式的前馈方式非数据辅助定时估计器。仿真结果表明对于BSPK调制，所提出的定时估计方法不受相位偏差的影响，每个符号需要4个采样点，实现复杂度很低，且定时抖动性能较好；对于QPSK调制方式，在载波相位得到较好恢复时也具有较好的性能。
novel non-data-aided (NDA) feedforward timing estimator which is suitable to binary phase shift keying (BPSK) and quadrature phase shift keying (QPSK) modulations is proposed. For BPSK, this estimator is insensitive to phase offset. This proposed timing estimator needs 4 samples per symbol with much lower complexity in contrast with conventional ones. For QPSK modulation, the timing jitter performance of this proposed estimator is better after perfect carrier phase recovery.
