ARINC-美国航空无线电通信公司（Aeronautical Radio Inc），美国军队的长期合作伙伴。ARINC664系列协议是ARINC公司负责制定的下一代航空数据网络标准。该规范分为8个部分，从不同层次对航空数据网络标准的各个方面进行了系统的定义，形成了以AFDX技术为核心的下一代航空数据网络的完整标准。(ARINC-Aeronautical Radio Inc, the U.S. military long-term partners. ARINC664 series protocol is ARINC company is responsible for the formulation of the next generation of airborne data network standard. This specification is divided into eight parts, from different levels of airborne data network standard all aspects of the definition of the system, formed the AFDX technology at the core of the next generation of airborne data network complete standard.)

通信系统仿真原理与无线应用 《通信系统仿真原理与无线应用》系统地介绍通信系统的设计、分析和仿真方法，还提供了大量极具参考价值的仿真实例。(Simulation principles of communication systems and wireless applications. "A systematic introduction to the design, analysis and simulation of communication systems, it also provides a large number of simulation examples of great reference value.)

实现16QAM完整的调制解调系统，包括基带信号串并转换，星座图映射，升抽样成形滤波，升采样半带滤波，数字上变频，功放的多项式非线性效应，加性高斯白噪声信道，接收端下变频，降采样，匹配滤波，绘制接收端星座图。(16QAM modulation and demodulation realize the complete system, including the baseband signal string and conversion, constellation mapping, sampling shaping filter liter, half liter sampling with filtering, digital up-conversion, amplifier polynomial nonlinear effects, additive white gaussian noise channel, the receiver end down-conversion, down-sampling, matched filtering, draw the receiver constellation.)

利用MATLAB实现多用户的扩频通信的发送和接受，程序可以直接跑，不需要改动！(The use of MATLAB implementation of multi-user spread spectrum communication send and receive, the program can be directly run, no changes!)

说明：  开环/闭环下的MIMO信道的信道容量。未知CSI时的MIMO信道容量。(Channel capacity of MIMO channel in open / closed loop. MIMO channel capacity at unknown CSI.)
