这个是语音增强里面的基本谱减法程序，可以直接编译运用，效果显著(This is the voice inside to enhance the basic spectral subtraction procedures, the compiler can directly use the results significantly)

My programs are about signal and image processing.

OFDM系统的仿真代码MATLAB环境下(OFDM system simulation environment MATLAB code)

A MATLAB program has been written to investigate Orthogonal Frequency Division Multiplexing (OFDM) communication systems. This program is valuable for future researchers simulating systems that are too theoretically complex to analyze. Single-carrier QAM and multicarrier OFDM are compared to demonstrate the strength of OFDM in multipath channels. Two graphical user interface demonstrations show some of the basic concepts of OFDM.
