说明：  TCPIP在51单片机中的使用，一看就会，非常简单可靠实用(TCPIP )

LTE ADVANCED ,LTE PHY Downlink with Spatial Multiplexing

插值滤波器，可以改变样值的抽样速率问题，比如把2倍抽样的样值转换为2.5倍抽样的样值。(Interpolation filter, can change the kind of questions the value of the sampling rate, such as 2 times the sample put the kind of value is converted to 2.5 times the sample value of the sample.)

说明：  HHT变换的核心是EMD,在此项过程中通过EMD的编程和HHT的编程来实现了希尔伯特黄变换,可以看出处理此方法用来处理非线(The core of HHT transform is that EMD, realizes Hilbert Huang transform through EMD programming and HHT programming in this process. It can be seen that this method is used to deal with non-linear.)

信道均衡的讲义，将均衡讲的出神入化，非常之好(Channel equalization of the handouts, will talk about the superb balance, very good)

visual C++ MFC 环境下 串口的连接，收发数据的实现，串口探测工具部分功能的实现(Serial port connection)

说明：  7. 单径瑞利信道中的两发一收STBC： (1) 分析误码率的理论性能，画出比特信噪比与误码率的关系曲线。 (2) 请设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线。(7. Two outgoing and one outgoing STBC in single-path Rayleigh channel: (1) analyze the theoretical performance of bit error rate and draw the curve of the relationship between bit SNR and bit error rate. (2) please design a specific navigation-assisted channel estimation method, Simulink simulation, measurement of BPSK modulation error rate performance.The relation curve between the bit signal-noise ratio and the mean square error of channel estimation is drawn, and the relation curve between the bit signal-noise ratio and the bit error rate is drawn.)
