说明：  熟悉OQPSK的基本原理、调制解调技术，掌握MATLAB中M文件的使用及相关函数的调用方法，在此基础上通过MATLAB编程来实现OQPSK的调制与解调(The goal of this design is to deeply understand the basic principle of OQPSk modulation and demodulation, learn how to use MATLAB software in the M file to realize OQPSk modulation and demodulation analysis and join the influence of different noise on the signal, the first to create a digital baseband signal and then the corresponding function in MATLAB the baseband signal modulation, and then analyses the waveform of the modulated, record the results of modulated signals after demodulation, observe the demodulation results and record, finally adding noise in the signal and then observe the changes of the time-frequency diagram, analyze the noise of the signal to noise ratio influence the result of the modulation.)

这是一个MATLAB的IIR滤波器的程序!(This is a program of IIR fliter!)

It will ask for input the bit stream then generate pseudorandom bit sequence, finally give output as direct sequence spread spectrum
