| 摘 要： | 提出了一种直接对过采样的连续相位调制(CPM)信号进行单载波频域均衡的算法,同时提出了一种在插入循环前缀后发送CPM信号的相位仍然连续的方法。仿真结果表明,该单载波频域均衡算法能有效地消除大时延信道冲击响应下的CPM接收信号中的码间串扰。与现有的基于匹配滤波、符号抽样的CPM信号的单载波频域均衡算法相比,其性能和复杂度相当,但是CPM接收机的前端更为简单。

| Abstract: | A single carrier frequency domain equalization （SC-FDE） algorithm is proposed for oversampling continuous phase modulation （CPM） signals directly, and the methodology for maintaining phase continuity with a cyclic guard interval is also presented. Simulation results show that SC-FDE algorithm is an effective approach for CPM on channels with long impulse responses. Compare with those SC-FDE algorithms also proposed for symbol spaced samples of CPM, it has similar performance and complexity, but it can simplify the front end of CPM receivers. |
