摘　　要：正交码时分多子信道扩谱调制信号是一种新的宽带抗干扰信号,其频谱具有类高斯白噪声特性。文章首先介绍了系统的Systemview仿真模型及仿真结果,在此基础上,基于软件无线电的思想,提出了该信号接收模块的设计方法,并从硬件实现的角度较详细地阐述了该信号数字中频接收模块的原理与FPGA的实现方案。仿真结果证明了该方案的可行性和有效性。An orthogonal code time division multi-subchannel spread spectrum modulation（OC-TDMSCSSM） signal is a new of broadband anti-jamming signal, and its spectrum possesses analogous white Gaussian noise spectrum characteristics. The Systemview simulation model is presented first, and then their simulation results are derived. Based these and in the light of software radio the receiver design scheme for OC-TDMSCSSM signal is proposed, and then its principle and FPGA implementation is described in detail from the angle of hardware. Simulation results indicate that this method is feasible and efficient.
