本程序是一个基于空时编码的MIMO-OFDM通信系统的仿真设计，包括QPSK调制解调，IFFT调制，空时编解码(This procedure is based on a space-time coded MIMO-OFDM communication system simulation design, including QPSK modulation and demodulation, IFFT modulation, space-time codec)

In this code we used a fingerprint as cover and a text image as hidden image by using wdt to enhance security for sending our text.

matlab实用程序小合集第3部分，都是一些完成特定功能的小程序，很适合新手朋友(matlab utility small collection Part 3, are some small programs to accomplish a specific function, it is suitable for novice friend)

说明：  最优化算法，使用信赖域法（LM）求解无约束问题。可以实现画出三维图像，通过修改初始点，得到迭代次数和函数值(Optimization algorithm, using LM method to solve unconstrained problems. Three dimensional images can be drawn, and the number of iterations and function values can be obtained by modifying the initial points.)

S 变换是 Stockwell（1996）等提出的一个时-频分析方法，它结合了短时 Fourier 变换和小波变换的特点，能够完全无损地实现逆变换。(S-transform is a time-frequency analysis method proposed by Stockwell (1996). It combines the characteristics of short-time Fourier transform and wavelet transform, and can realize inverse transform completely without loss.)
