对16QAM调制解调技术，主要实现了16QAM的调制(16QAM modulation)

代码里有很完整的注释和解释，欢迎大家下载学习，ldpc码的编解码实现。( Code, there are very complete notes and explanations Welcome to download the study, Codec ldpc code implementatio.)

说明：  此程序描述基于最大似然准则的频率估计。该算法可以估计短突发信号的载波频偏，这种算法估计的精确度高。(This procedure describes the frequency estimation based on the maximum likelihood criterion. This algorithm can estimate the carrier frequency offset of the short burst signal, and the accuracy of this algorithm is high.)

线性方程组的cg解法matlab，可以用于cg方法来计算线性方程组(Cg solution of linear equations matlab)

文件为关于如何用matlab进行编程的资料，用matlab编程比用C语言更容易，它的矩阵运算能力更是c语言难以比拟的。再用matlab编程时，一些小细节忘了可以看一下此文件。(Document on how to use matlab to program information with the matlab programming language more easily than C, its capacity is c matrix operations can not match the language. Then matlab programming, forgot some small details can look at this file.)

Cognitive Radio used widely in Communication Engineering

说明：  有源功率因数校正仿真模型，采用滞环电流控制的方法。(The simulation model of active power factor correction adopts the method of hysteresis current control.)
