摘要

本文提出了一种带校正的差分相移键控(MDPSK)信号的决策反馈差分检测方法。将该方案与经典的决策反馈差分检测(DF-DD)接收机进行了比较。结果表明,该接收机在频偏存在的情况下,在很宽的频偏范围内具有较好的性能。所提出的接收机并不比普通的DF-DD接收机复杂多少,因为只引入了一个更复杂的乘法。

Application of corrected decision feedback differential detection algorithm for the detection of MDPSK signal
In this paper, decision-feedback differential detection with correction of M-ary differential phase shift keying (MDPSK) signals is proposed. Proposed scheme is compared with classic decision feedback differential detection (DF-DD) receiver. Results show that the proposed receiver has better performances in the presence of frequency offset, in a very wide range of frequency offsets. The proposed receiver is not much more complex than the ordinary DF-DD receiver since only one more complex multiplication was introduced.
