摘　　要：从提高无线通信系统的抗干扰能力出发,引入正交码时分多址信道扩谱调制新技术,提出了一种新型抗干扰技术和模型。首先给出了新系统的发射机和接收机模型,导出了对应的信号格式。并以加性高斯白噪声信道为背景,系统分析了新系统的误码率性能。理论分析与仿真表明,该方案与传统DS/FH系统相比,具有更优的误码性能。To improve the anti-jamming ability of wireless communication system, the technique named orthogonal code time division multi segmented channel spread spectrum modulation is introduced, and a new anti-jamming technique and model is proposed. The transmitter and receiver model are presented first, as well as the corresponding signal format. And providing adding Gaussian white noise channel, the BER performance analysis of receiver is given in the case of non-coherent reception and coherent reception re- spectively. Analysis and simulation show that the proposed model and scheme has better BER performance than that of traditional DS/FH system..
