扩展的空间调制，打破了传统空间调制技术发送天线数目必须是2的幂数的限制，提高了频谱利用率。(The extented spatial modulation breaks the constraint of the traditional spatial modulation in which the number of the transmit antenna must be a power of 2 enchancing the spectrum efficiency.)

数字调制技术的发展日新月异现如今信息技术不断的推陈出新，信息的传输及通信起着支撑作用。而对于信息的传输，数字通信已经成为重要的手段。因此，数字信号的调制就显得非常重要。数字调制是通信系统中最为重要的环节之一，而实现数字调制需要的方法就需要用键控法来实现，比如可以对载波的振幅、频率和相位进行键控。(ASK , FSK , PSK modulation and demodulation of the simulation comparison )

计算增强后语音的IS距离，用于评价语音质量(Calculating the IS-distance of enhanced speech for evaluating speech quality)

It is a matlab code to simulate kalman filter. It can be run in matlab 2007 or higher

说明：  一套非常漂亮实用的图片站源码，以前本人用过的，而且排名很好！(A very nice picture stop source of practical, previously I used, but also a very good position!)

平界面下的正演,自己编写的，。。。在matlab下能够运行(Forward under the flat interface，Write your own,... To be able to run under Matlab)

卡尔曼滤波评估，用于精密单点定位,提高了定位精度，在某工程上已经得到验证(Kalman filter evaluation for precise point positioning, positioning accuracy has been verified on a project)
