摘　　要：改进数字传输接收系统抗干扰的方法,是利用相移键控信号和互比特伪随机频率调谐以及频率子信道中的窄带干扰自适应补偿器。文中主要研究利用符号间的PWFT证实接收的PM信号的结构图,用非线性补偿算法对窄带干扰频率的不变性,来确保在窄带干扰作用条件下抗干扰的可靠性。For improving the interference immunity of trans/rec systems in the transmission of digital information, the phase-shift keying signal, interbit pseudorandom frequency tuning and adaptive compensator of narrow-band interference in the frequency subchannel are generally used. This paper mainly discusses the confirmation of PM structure chart by using symbols PWFT, and the handling of narrow-band frequency interference invariance by using non-linear compensation algorithm, and thus for ensuring the anti-interference reliability under the narrow-band interference role.
