Ekahau postioning engine user guide

说明：  结合回声消除和语音增强方法的double talk算法，能在噪声环境下定出语音的端点(light echo cancellation and voice enhancement method of double talk algorithm can be noisy environment set voice endpoint)

Matlab功能与法法上传，请采用 希望采用挺好挺全的(Matlab function and method of upload, please use)

Steven Ding基于模型的故障诊断的最新作品第二版(model_based fault diagnosis the second Edition of Steven X. Ding)

用burg算法实现功率谱的估计，可以改变信噪比SNR，阶次P，可以分析分辨率(Burg algorithm using power spectrum estimation, can change the signal to noise ratio SNR, order P, can be analyzed resolution)

differents types of filters for matlab.

pca主成分分析，matlab程序，用于图像特征提取，降维等 有中文注释(Principal component analysis)

说明：  本程序实现的功能是：bpsk在matlab上的调制解调(modulation and demodulation of bpsk on matlab.)
