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.

Study-on-the-Control-Scheme
恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略，以重复控制器提高逆变电源输出电压的稳态精度，减小总谐波畸变率；以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240 DSP控制芯片的50 Hz三相PWM逆变器上得到验证。(Constant voltage constant frequency (CVCF) Inverter output voltage waveform quality is an important measure of its performance indicators. Paper using a repetitive control and the combination of double closed loop control voltage waveform control strategy to improve the repetitive controller output voltage inverter steady-state accuracy and reduce total harmonic distortion to achieve a faster dual-loop controller dynamic response speed. The program uses TMS320F240 DSP in a 50 Hz phase control chip PWM inverter has been to verify.)
