一本很好的基于matlab的通信原理模型，里面有所有模型的代码(A good model of communication theory based on matlab, there are all models of the code)

给出了BPSKMSKQAMGMSK的详细代码，可以直接在MATLAB中运行，并且有误码率的仿真。(BPSKMSKQAMGMSK given a detailed code, can be run directly in MATLAB, and BER simulation.)

通过具体的信道实例对比几种信道容量，绘出对数正态衰落、瑞利衰落、Nakagami衰落下确定的容量随平均接收信噪比变化的曲线。(The capacity of several channels is compared by a specific channel example, and the curve determined by the logarithmic normal fading, Rayleigh fading and Nakagami fading with the change of the average received signal to noise ratio (SNR) is drawn.)

ADMM算法 切普信号的参数估计问题 包括个数估计和频率估计(The parameter estimation of Chep signal based on ADMM algorithm includes number estimation and frequency estimation.)

说明：  自己用的小软件，仿造原子的XCOM功能，加了一下自己用的功能。 1、基本串口通讯，鼠标放入串口选择自动刷新，显示COM口的驱动类型。 2、多条发送界面，可定时发送，可关联数字键盘、右键发送按钮可更改按钮名称，方便记忆。 3、485通讯，数据有十进制和十六进制可选，发送后自动保留记录。 4、CRC校验小工具。 5、十六进制通信协议提取部分位并根据自定义数据类型转化为十进制 6、字符格式示波器，例：">P:-1.25"，示波器显示曲线名称P，数值-1.25，曲线个数最多8个。 7、类似MODBUS协议截取第2-5位，合成一个int数值，然后示波器显示波形，最多5个曲线 8、示波器曲线可键拖拽、放大(QT serial port assistant, plus digital oscilloscope)

分析仿真了LTE-Advanced系统部署Pico后的小区间干扰协调技术.本文针对在LTE—Advanced系统中部署Pico后恶劣的干扰条件进行了详细的分析，并重点讨论了三种可以有效兼容R8／R9终端的增强型ICIC技术。(Analysis and simulation of LTE-Advanced systems deploy Pico Inter-cell interference coordination techniques for LTE-Advanced systems deploy Pico bad interference conditions, carried out a detailed analysis, and focused on the three can be effectively compatible with R8/R9enhanced terminal ICIC technology.)

说明：  High Definition Multimedia Specification Version 2.0
