实现物理层网络编码的仿真，此为无信道编码环境下实现的(network coding)

使用matlab进行毫米波信道模型仿真，很棒的源码(Millimeter-wave channel model simulation using matlab, great source code)

Winner+通信信道模型文件，视距通信概率，非视距通信概率，路损模型等(Winner+ communication channel model file, line of sight communication probability, the probability of non-line communication, road loss models)

使用QPSK调制方式的简单的通信系统，包含载波同步位同步等模块(a simple communication system, using QPSK modulation, including bit synchronization and carrier synchronization)

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.)
