K最邻近节点算法（KNN）分类器

说明：  介绍wimax通信路推定的好文章，开发语言是Matlab.对于搞wimax通信路推定的人是个很好的借鉴文章(Wimax way to introduce a presumption of good communication articles, the development of language is Matlab. To engage in communications wimax Road presumption is a very good reference article)

说明：  We describe a new method for performing a nonlinear form of Principal Component Anal

考察Rayleigh衰落信道下，采用实际产生的信道参数进行解码的BER性能（理想信道估计）(Examine Rayleigh fading channels, using the effective channel parameters generated decoding BER performance (ideal channel estimation))

在瑞利信道条件下采用差分调制，LDPC编码系统的BP译码算法的实现。(Differential modulation in Rayleigh channel conditions, achieve BP decoding algorithm for LDPC coding system.)

自己编的最小二乘参数辨识，已经调试，内附详细程序说明。(Their own series of least-squares parameter identification, has been commissioning, containing detailed description of the procedures.)

本程序用MATLAB读写串口。具体功能为读一个传感器。首先发送读指令，然后等待传感器反应。用MATLAB定时器定时，每秒读写1次。程序中使用了回调函数，包括串口接收回调函数和定时器回调函数。

RLS算法，编写了MATLAB程序实现自适应干扰对消。给出信号实例，用于验证所编写程序的性能。所给信号为：①噪声与语音的混合信号——signalnosie.wav；②噪声信号——noise.wav。两信号均为立体声，PCM压缩，采样速率为48000Hz，采样精度16bits。(RLS algorithm, the preparation of a MATLAB program to achieve adaptive interference cancellation. Given signal instance, prepared by the procedures used to validate performance. The given signal as follows: ① noise with the voice of mixed-signal- signalnosie. Wav ② noise signal- noise. Wav. Two signals are stereo, PCM compression, sampling rate of 48000Hz, the sampling precision of 16bits.)
