通过MONTE GARLO仿真，说明一个使用二进制FSK并受到最坏部分频带干扰破坏的FH数字通信系统的性能。(MONTE GARLO through the simulation shows that the use of a binary FSK and are subject to the worst part of band interference and sabotage by FH digital communication system performance.)

基于粒子群算法的matlab实现，很好用！谢谢！(Based on particle swarm algorithm matlab realize, good use! Thank you!)

design fir filter with matlab

The MOLMAP multiway toolbox is a collection of MATLAB modules for calculating MOLMAP scores on multiway data. The scores can be used in subsequent regression or classification models.

说明：  d基于matlab的dtft算法，已通过验证，放心可用(dtft)

不同窗函数数下，自功率谱，互功率谱，频响函数和相干函数，绘制功率谱图(Not under the old function, since the power spectrum, cross-power spectrum, frequency response function and coherence function, map power spectrum)

输入自己事先录制好的语音信号，该程序实现将语音信号通过FIR低通、高通、带通滤波器后还原出来的语音质量(Enter their own pre-recorded speech signal, the program will realize voice signal through the FIR low-pass, high pass, band-pass filter to restore them after the voice quality)

说明：  高斯滤波器对图像的去噪效果,具有很好的效果。(denoise on filter of gaussian)

说明：  利用短时能量和短时过零率的语音端点检测算法(Short-term energy and zero crossing rate of the voice activity detection algorithm)
