Okumura&Hata模型

说明：  本文件是基于高斯正弦波行的宽带脉冲波形设计,保证了相对带宽大,衰减满足3db要求(this document is based on the Gaussian line broadband sinusoidal pulse waveform design, ensuring a relatively large bandwidth. attenuation meet the requirements Z)

技术文档：OFDM联合极大似然法，符号和载波频偏估计，利用循环前缀的冗余信息实现ML估计，不需额外插入导频，其频率估计用于跟踪模式，时间估计用于捕获模式。(OFDM ML estimator for time and frequency)

封装了windows操作串口的几个API（CreateFile， ReadFile，WriteFile，SetComState）。串口的读写设置这几个操作都可以简单地只用关键一两个参数就能实现操作。也是一个很好的例子，我写这个之前查了不少资料，感觉非常麻烦，索性发出来给新手们作个样例(Windows serial COM port access class，it includes CreateFile, SetComState，ReadFile，WriteFile，CloseFile)

Performance Evaluation of DWT

ONVIF的测试工具12.06版本,测试是否支持ONVIF协议及其他.(12.06 version of ONVIF test tool, test to support ONVIF protocol and other.)

74ls273的器件数据手册，是英文的7 4ls273的器件数据手册，是英文的74ls273的器件数据手册，是英文的(74ls273 device data manual is in English 7 4ls273 device data manual is in English 74ls273 the device data manual is in English)

for entropy H = entropy(S) this command will evaluate the entropy of S, S should be row matrix H = entropy([X Y Z]) this command will find the joint entropy for the 3 variables H = entropy([X,Y],[Z,W]) this will find H(X,Y/Z,W).. you can use it for any combination of joint entropies Please validate this function before using it

本文分析了多级维纳滤波器的特性，在加性噪声和二维天线阵列如均匀圆阵、均匀面阵、十字阵等条件和背景下，对信源个数和信源参数估计问题进行了研究，提出了基于多级维纳滤波器前向分解特性的快速参数估计方法，同时提出了基于多级维纳滤波器的二维ESPRIT参数估计方法，该类方法无需协方差矩阵的估计运算及分解运算，计算复杂度较低。另外，还提出了对信源个数的估计算法。(This paper analyzes the characteristics of multistage Wiener filter, in the additive noise and the two-dimensional antenna array such as a uniform circular array, the uniform array, cross array conditions and background, the source number and source parameter estimation problem undertook study, put forward based on Multistage Wiener filter prior to the decomposition characteristics of fast parameter estimation method, at the same time based on Multistage Wiener filter 2D ESPRIT parameter estimation method, the method does not need to estimate of covariance matrix calculation and decomposition, relatively low computational complexity. In addition, also put forward for source number estimation algorithm.)
