23825728MIMOcapacity

利用C++实现的一个即时通讯系统的客户端。传输层采用的是TCP协议。这是本科时候的毕业设计，最后评定为优，希望对一些朋友能有所帮助。(The use of C++ implementation of an instant messaging system client. Transport layer protocol used is TCP. This is the time of undergraduate graduation project, and finally classified as gifted, in the hope that some of my friends can be helpful.)

The future satellite communication systems are re- quired to support the higher transmission data rate for providing the multimedia services by employing the e铿僣ient modulation method such as multi-level QAM.

中文RFC文档，不用翻译，对大家学习很有帮助！(Chinese RFC documents, without translation, the right to study very helpful!)

说明：  MIMO系统由于在空间中具有多个发送和接收天线，因此其信道模型也具有其特有的复杂性。尽管具有这种复杂性，对MIMO信道进行建模仍然十分必要。(Because MIMO system has multiple transmit and receive antennas in space, its channel model also has its own complexity. Despite this complexity, it is still necessary to model MIMO channels.)

实现的通信中正交频分复用的过程，包括OFDM的一些信号处理的算法(To achieve communication in orthogonal frequency division multiplexing process, including a number of OFDM signal processing algorithms)
