Given an output function f(x) and a cost function J(x) (and gradients), optimal inverse functions are found which produce the input x* with the lowest cost based on the current desired output. Output and cost functions produce a scalar. The method is demonstrated on 2D problems (for convenient visualization). With 2D plots removed (all but Figure 41), the code can run higher dimension systems also.

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.)
