| 摘 要： | 介绍了扩展二元相移键控调制(Extended BPSK调制,以下简称EBPSK调制)信号模型及其二阶循环谱特性。对平稳信号匹配滤波进行拓展的基础上,提出了一种新的基于循环谱特性的EBPSK解调算法,由此给出基于该解调算法的EBPSK接收机框图,并对该解调算法性能进行了分析,最后进行了仿真验证。理论分析及仿真结果表明:基于循环谱特性的EBPSK解调算法利用噪声与EBPSK信号在循环频率域上的差别,能够有效分离在频域和时域都重叠的噪声和EBPSK信号,为EB-PSK调制的实用化提供一种有价值的参考。

| Abstract: | This paper introduced the signal model and cycle spectrum characteristic of extended binary phase shift keying(EBPSK) signals.By extending matched filtering theory of stationary signals,a new demodulation algorithm for EBPSK based on cycle spectrum characteristic is presented.Receiver block diagram of EBPSK according to the algorithm is proposed,and the performance of the demodulation algorithm is analyzed.Simulation results demonstrate the validity of the algorithm.Theoretical and simulation results show t... |
