This project demonstrates OFDM with adaptive modulation applied to Multiple-Input Multiple- Output (MIMO) systems. The analysis and simulation is considered in two stages. The rst stage involves the application of a variable-rate variable-power MQAM technique for a Single-Input Single-Output (SISO) OFDM system. The second stage applies adaptive modulation to a general MIMO system by making use of the Singular Value Decomposition to separate the MIMO channel into parallel subchannels.

说明：  王永良编的《空间谱估计理论与算法》，包括课本与代码(Theory and algorithm of spatial spectrum estimation, edited by Wang Yongliang, includes textbook and code)

方便好用的声学多普勒海流剖面仪（ADCP）海流数据Matlab处理程序。程序文件头信息有详细的使用说明。( ADCP=RDRADCP(NAME) reads the raw binary RDI BB/Workhorse ADCP file NAME and puts all the relevant configuration and measured data into a data structure ADCP (which is self-explanatory). This program is designed for handling data recorded by moored instruments (primarily Workhorse-type but can also read Broadband) and then downloaded post-deployment.)
