说明:  本文阐述了扩展频谱通信技术的理论基础和实现方法,利用MATLAB 提供的可视化 工具Simulink 建立了扩频通信系统仿真模型,详细讲述了各模块的设计,并指出了仿真建模 中要注意的问题。在给定仿真条件下,运行了仿真程序,得到了预期的仿真结果。同时,利 用建立的仿真系统,研究了扩频增益与输出端信噪比的关系,结果表明,在相同误码率下, 增大扩频增益,可以提高系统输出端的信噪比,从而提高通信系统的抗干扰能力。 (This paper describes the theory of spread-spectrum communication technology and implementation methods based on the use of visualization tools provided by MATLAB Simulink to establish a spread spectrum communication system simulation model, described in detail the design of each module, and pointed out that the simulation modeling to note problem. In the given simulation conditions, running a simulation program to obtain the desired simulation results. Meanwhile, the use of the simulation system to study the spreading gain and the relationship between the output signal to noise ratio, results show that the same bit error rate, increased spreading gain can increase the system output signal to noise ratio, thereby enhancing communication system disturbance.)

    雷达信号处理,针对现代雷达信号处理的主要方式,运用数字信号处理理论和 Matlab 软件研究雷达信号处理的仿真 问题。提出了一个仿真模型,该模型可以仿真雷达信号、热噪声与杂波的产生和雷达系统中信号的动态处理 过程。用 Matlab 对某脉冲压缩雷达信号处理系统进行了仿真,得到了雷达系统中各个处理点上的具体信号形 式,既包含幅度信息,又包含相位信息,该模型能较好地满足对雷达信号处理的仿真要求,显示了用 Matlab 仿真雷达信号处理系统的方便、快捷的优点。 (Radar signal processing, radar signal processing for the modern major mode of use of digital signal processing theory and Matlab software simulation of the radar signal processing problems. Proposed a simulation model, the model can be simulation of radar signals, thermal noise and clutter of the radar system in the generation and dynamic signal processing. Using Matlab for a pulse compression radar signal processing system simulation, radar systems have been various points on the treatment of specific signal form contains both amplitude information, but also contains the phase information, the model can better meet the needs of radar signal processing simulation requirements, shows the Matlab simulation using radar signal processing system convenient, fast advantages.)
