CODE FOR CR TFF FOR IMAGE POCESSING

本文主要利用matlab编程工具对直接序列扩频通信的捕获过程进行仿真。仿真主要基于滑动相关法的有关理论,先讨论扩频仿真中起着重要作用的m序列的生成问题,尔后讨论调制信号的产生,然后在信号的捕获中分步讨论,先对捕获的流程进行简单的仿真,再依次加入噪声和多普勒频移后进行捕获仿真(In this paper, using matlab programming tools for direct sequence spread spectrum communication capture process simulation. Simulation of the sliding correlation method is based on the theory, first discuss the simulation plays an important role in spreading the m sequence generation problem, the modulation signal generation and later discussed, and the signal captured by stepping discussion processes the captured first simple simulation, and then followed by adding noise and Doppler frequency shift after the capture simulation)

对图像加入白噪声干扰，用维特比译码进行去扰，分别用硬判决和软判决，显示出的图像可以看出不同的效果(White noise is added to the image, performed using Viterbi decoding descrambling, respectively, with the hard decision and soft decision, showing the different effects can be seen in the image)

完成了扩跳频系统的误码率仿真，并且对比了窄带干扰和没有窄带干扰情况下的误码率曲线，仿真了频谱
