用matlab生成gold序列，并绘出其自相关和互相关曲线(Gold sequence generated by matlab, and draw their autocorrelation and cross-correlation curves)

说明：  自写Matlab的FFT代码，供分享，仅供参考。(Write Matlab FFT code, for sharing, for reference only.)

此函数是用C语言编写的MEX文件，与MATLAB中imreconstruct函数功能相同，效果一样，运行速率更快。(This function is written in C MEX file, the same function with in MATLAB imreconstruct function, the same effect faster run rate.)

压缩感知程序源码，Blind compressed sensing (BCS)不需要在采样和恢复阶段预先知道稀疏基。源码对于研究压缩感知前沿具有很好的借鉴意义。(The fundamental principle underlying compressed sensing is that a signal, which is sparse under some basis representation, can be recovered from a small number of linear measurements. However, prior knowledge of the sparsity basis is essential for the recovery process. Blind compressed sensing (BCS) avoids the need to know the sparsity basis in both the sampling and the recovery process. That is, BCS aims at recovering an ensemble of vectors, all sparse under the same unknown basis, given small number of linear measurements of these vectors. )

说明：  FM和PM的调制解调仿真源代码，已经调试通过。(FM and PM modulation and demodulation simulation source code has been debugged.)
