These are some code for direct sequence spread spectrum system using different methods which can be used for DSSS signal interception.

说明：  二维冲突概率算法，其实这个仿真是为了验证三维算法实现的基础，在二维的基础上再把二维扩展到三维。但也有不一样的地方(Two-dimensional conflict probability algorithm, in fact, this simulation is to verify the basis of three-dimensional algorithm, based on the two-dimensional two-dimensional and then extended to three-dimensional. But there are also not the same place)

包含例程用于雷达测距方法,理论分析清晰,请仔细阅读(contains routines for radar location, a clear theoretical analysis, please read carefully)

详细介绍了Simulink工具箱，对于系统仿真很有用(Details the Simulink toolbox it is useful for system simulation)

信号与系统基础练习，演示了数字信号处理中常用的傅里叶变换，分析时域和频域的信息(Signals and systems based practice, demonstration of digital signal processing used in the Fourier transform of the time domain and frequency domain information analysis)
