用matlab实现了16-QAM的调制解调过程，效果良好。(Achieved using 16-QAM matlab modulation and demodulation process to good effect.)

只需要使用Matlab 就可以播放 wave 檔.不需要Media Player或音樂撥放軟體.(Use Matlab to play wave file. This is an example to play 1k tones by using Matlab.)

这是matlab的高级编程，适合于已经熟练掌握的专业人士(This is a matlab advanced programming, suitable for professionals have mastered)

本代码是基于RSSI的无线定位代码，包括PPT和论文说明，代码里边还好有GUI仿真代码。( The code is based on the RSSI of wireless location code, including PPT and papers instructions, but fortunately there are GUI code inside the simulation code.)
