摘　　要：针对影响矿井下通信质量的环境噪声问题,采用窗函数法,借助Matlab软件设计出所需的FIR滤波器,得出滤波器系数,然后导入DSP程序中并加载到DSP芯片TMS320VC5402上实时运行。实践证明,所设计的滤波器能够较好地滤除高频噪声,改善矿井下的通信质量。Aiming at the environmental noise problem affecting the quality of communication of mine underground,use the method of window function, with the help of Matlab software to design the FIR filter,get the filter coefficients, and then import the DSP program and load into the DSP chip TMS320VC5402 in real-time operation. Practice has proved that the designed filter can filter out high frequency noise, improve the quality of communication of mine underground.
