说明：  用优化算法求解运输问题。 1.不使用linprog，比较歧异解 2.用西北角法求初始基本可行解，用闭回路法确定退出基和更新运输矩阵 3.不能处理非平衡的运输问题(Optimization algorithm used to solve transport problems. 1. Do not use linprog, compare differences solution 2. With the northwest corner of France seeking an initial basic feasible solution, using closed-loop method to determine the transport out of the base and update the matrix 3. Can not handle the transport of non-equilibrium)

说明：  show the result of using DF in cooperative communications

最新大规模天线阵列信道建模论文集，对研究大规模天线信道容量颇有帮助.(The latest paper set of Massive MIMO channel modeling. It is very useful for those who are interesting in Massive MIMO channel capacity.)

说明：  波达方向（DOA） 估计的基本问题就是确定同时处在空间某一区 域多个感兴趣的信号的空间位置(即多个信号到达阵列参考阵元的方 向角)。最早的也是最经典的超分辨率(DOA)估计算法是著名的多信号 分类（Multiple Signal Classification） 法,简称 MUSIC 算法,它是 一类经典的基于特征结构分析的空间谱估计方法。该算法利用了信号 子空间和噪声子空间的正交性,构造空间谱函数,通过谱峰搜索,检测 信号的 DOA。(The basic problem of DOA estimation is to determine the simultaneous location in a certain region of space. Spatial position of multiple interested signals in the domain (i.e. the direction of multiple signals reaching the array reference elements) Directional angle). The earliest and most classical super-resolution (DOA) estimation algorithm is the well-known multi-signal.Multiple Signal Classification, referred to as MUSIC algorithm, is A classical spatial spectrum estimation method based on eigenstructure analysis. The algorithm utilizes signals. The orthogonality of subspace and noise subspace, the construction of spatial spectral function, through peak search, detection DOA of signal.)
