| 摘 要： | 首先介绍了扩展的二元相移键控(EBPSK)调制波形及脉冲干扰模型,提出了一种简单的基于冲击滤波器和限幅的抗干扰传输模型,从理论上分析了该系统对抗脉冲干扰的优势.仿真实验表明,在严重的脉冲干扰情况下,EBPSK系统表现出超强的抗干扰能力,同时,也通过误码率曲线表明了基于限幅的系统模型的有效性,从而为超窄带的EBPSK系统迈入实际应用阶段奠定了基础.

| Abstract: | In this paper,extended binary phase shift keying(EBPSK) modulation waveform and impulsive interference model are introduced firstly,then a new and simple anti-interference transmission model based on the impact filter and amplitude limiting is proposed,and the advantages of this system against impulsive interference are analyzed.Finally,simulation results show that the EPBSK system exhibits very high ability of anti-interference in the case of serious impulsive interference.Simultaneously,the BER curves als... |
