PCM编解码（Pulse-code modulation），即脉冲编码调制）(PCM codec (Pulse-code modulation), Pulse Code Modulation))

信号时正弦波加正态零均值白噪声，信噪比10db，信号频率2kHZ，采样频率100kHZ，数据长度N=256。 (1). 用周期图法进行谱估计。(Sine wave signal plus zero-mean normal white noise, SNR 10db, frequency 2kHZ, sampling frequency 100kHZ, data length N = 256. (1) with the periodogram spectral estimation.)

从电脑中选择一个图片，本程序可对图片完成类型转换，几何运算，代数运算（平均法降噪和减数运算），傅里叶变换，图像增强（包括灰度值变换，直方图均衡化，邻域平均法和中值滤波波法），图像复原，图像分割等功能。(Choose a picture from the computer, this program can complete type conversion, geometric operation, algebraic operation (average noise reduction and reduction), Fourier transform, image enhancement (including gray value transformation, histogram equalization, neighborhood averaging and median filtering wave method), image restoration, image segmentation and other functions.)

16QAM的调制，它把输入的二进制数据以查找表的方式进行映射，从而提高信息传输率。(16QAM modulation, it is the input of binary data to find a way to map the table to enhance information transfer rate.)

移动通信--无线楼宇数据传输系统的仿真.分析915M的楼宇通信特性，建立楼宇数据通信系统的仿真模型，采用无线收发芯片NRF905，依据其性能参数来判断楼宇内两点之间能否进行数据传输。(mobile communications-- wireless data transmission system building simulation. Analysis of cellphone communications characteristics of the buildings, establish premises data communications system simulation models, the use of wireless transceiver chip NRF905. based on its performance parameters to judge between the two buildings can for data transfer.)

说明：  matlab实现K-L变换,可用于图像去噪，地震资料去噪(K-L transform. It can be used in noise reduction and image enhancement)

这个是自己实现的matlab与c++的一个接口。 是用c++语言实现的(This is the realization of our own Matlab and c of an interface. Is the C Language)
