MIMO(OFDM)simulator
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.

Optisystem中MatlabComponent模块的扩展应用
通过一个光相位调制器的实例，介绍利用Optisystem 中Matlab Component组件联合M atlab实现用户自定义光学组件的方法。对相位调制基本原理、相位调制器理论模型和实现模型的Matlab代码进行分析，介绍如何将用户自定义器件功能代码关联Matlab Component组件进行仿真，并利用自定义的相位调制器对理论分析进行验证。(Through an example of an optical phase modulator, this paper introduces the method of implementing user-defined optical components by using Matlab Component component in Optisystem combined with M atlab. The basic principle of phase modulation of the phase modulator, theoretical model and implementation model of Matlab code analysis, describes how to simulate the user device function code associated Matlab Component components, and the theoretical analysis was verified by using custom phase modulator.)
