QPSK_Transmitter

说明：  基于matlab的编程，信道仿真的，很好很强大(Matlab-based programming, channel simulation, very good very strong)

超声波系统下的FFT仿真程序,可以将主要频率的波长滤波出来(FFT simulation program of ultrasonic system, can filter out the main frequency wavelength )

只要输入信号的中心频率和带宽，自动生成带通滤波器采样率、信号保护带、采样率误差容限(Just enter the center frequency and bandwidth of the signal, automatically generated bandpass filter sample rate, signal protection zone, the sampling error margin rate)

MATLAB在工程应用中的学习指南，有代码，有详解，特别适合新人学习。(MATLAB applications in engineering study guide, there are code, explain, especially for newcomers to learn.)

利用黄金分割点法计算步长，用来求二次凸函数的最小值的线搜索方法(Using the gold partition point method, the step size is used for the minimum of two convex functions.)

说明：  包含两个MATLAB程序，具体内容见里面的txt文档，第一个程序近似算法结果很差(Contains two MATLAB program details see the inside of the txt document, the first result of poor process approximation algorithm)

说明：  关于OFDM仿真的完整代码，包括发送机接收机各个环节。(The complete code about OFDM simulation, including emitter receiver each link. )

matlab界面编程，详细的实例说明，可以给学习界面编程提供很好的帮助(matlab GUI)
