摘　　要：EBPSK脉冲调制信号是通过脉冲序列在码元周期内位置的不同来传递数字信息的,接收端对信号进行相关处理得到的相关函数体现了原始码元的位置信息,所以可用于EBPSK信号的检测,同时给出了检测的最佳位置门限,仿真实验将相关检测方法与抽样检测方法的性能进行了对比,实验结果表明相关检测性能较优,且具有一定的抗干扰能力。Due to the EBPSK pulse modulation signal through the pulse sequence in the symbol period in different positions to transmit digital information, the correlation function between the received signal and the original signal reflects the position information of the original code, so this method can be used for EBPSK signal detection, and gives the best position of threshold detection. The correlation detection method is contrasted with sampling detection method in simulation experiment;the results show that the correlation detection performance is better, and has certain anti-interference ability.
