摘要 为了提高扩展二元相移键控(Extended Binary Phase Shift Keying,EBPSK)系统的抗衰落性能,并简化解调器结构,提出了一种对称的扩展二元相移键控(Symmetric-EBPSK,S-EBPSK)调制方式,以"0"、"1"码元对称的调制波形为主要特征,采用简单有效的冲击滤波加比较判决的方法来完成解调,并从理论上推导了S-EBPSK系统的功率谱,及加性高斯白噪声(Additional White Gaussian Noise,AWGN)信道下系统的理论误码率公式.仿真结果表明了所提方案实现简单有效,且无论在AWGN信道还是衰落信道下,均表现出了明显的性能优势. To improve the anti-fading performance of symmetric extended binary phase shift keying(EBPSK)modulation system and simplify the demodulator architecture,a(S-EBPSK)is proposed in this paper.The modulation signals are characterized with symmetric waveforms,and the simple and effective demodulation method is proposed,which impacts the filter added with comparison detection method.Both the theoretical power spectrum expression and the BER expression are deduced in detail.It is demonstrated by simulation that this scheme is simplified and valid.In addition,the S-EBPSK modulation system has advantages in both the additional white Gaussian noise(AWGN)channel and fading channel.
