通信系统中常用的多进制数字相位调制的源代码 并结合ofdm系统 加入了相应的保护前缀（cp）和导频序列 应用于有关ofdm的信道估计等系统(Communication systems commonly used in multi-band digital phase modulation of the source code and combine OFDM system by adding a prefix corresponding protection (cp) and the pilot sequence used in the relevant channel estimation of OFDM systems)

该算法实现了拉格朗日插值并比较了龙格现象(The Lagrange interpolation algorithm and compared the Runge phenomenon)

说明：  BPSK原理仿真，采用的是相干解调和非相干解调(BPSK principle simulation, using coherent detection and non-coherent demodulation)

说明：  涡旋光束在光束的传播方向上有一个位相项e，而且它拥有一个光束轨道角动量，该matlab程序实现了从一个高斯基模变换到涡旋光束的基本功能。(The vortex beam has a phase term E in the direction of beam propagation, and it has a beam orbit angular momentum. The matlab program realizes the basic function of transforming from a Gaussian fundamental mode to a vortex beam.)

汽车振动的频谱分析。很有意思，里面函数简单适合初学者。(Spectrum analysis of vehicle vibration. Very interesting, which a simple function suitable for beginners.)

This file describ the BFSK_rayleigh.

自己写的 AXI master code(AXI master code)

optmization algorithm method "Davidon-Fletcher -Powell" DFP

说明：  能够很好的实现混沌数字水印技术 并且具有创新功能 (Can achieve the chaotic digital watermarking technology and innovative features)
