wiley 2014 新书 Understanding LTE with MATLAB，包含MATLAB 源代码以及相关协议解读，是从事LTE 研究人员的不可多得好书(wiley 2014 book Understanding LTE with MATLAB, MATLAB source code contains the interpretation and related agreements, is engaged in rare books LTE researchers)

柯尔莫哥洛夫熵（Kolmogorov熵，以下简称K熵）是刻划混沌系统的一个重要的量。在不同类型的动力学系统中，K熵的数值是不同的。本程序可以计算kolmogorov熵(Kolmogorov entropy (hereinafter referred to as K entropy) is an important quantity for describing chaotic systems. In different types of dynamical systems, the K entropy is different. This procedure can calculate Kolmogorov entropy.)
