OFDM_matlab
该程序基本涵盖了OFDM-16QAM系统传输的全过程，除了调制解调外，有添加循环前缀，加窗的过程。生成图像有各个阶段的时域、频域图，以及发射前后的星座图。(This basically covers the whole process of OFDM transmission- 16 qam system, in addition to the modem, have add cyclic prefix, plus the window procedure. Generate the image at various stages of time domain and frequency domain graph, and before and after the launch of the constellation diagram.)

power_brushlessDCmotor
A three-phase motor rated 1 kW, 500 Vdc, 3000 rpm is fed by a six step voltage inverter. The inverter is a MOSFET bridge of the SimPowerSystems™ library. A speed regulator is used to control the DC bus voltage. The inverter gates signals are produced by decoding the Hall effect signlas of the motor. The three-phase output of the inverter are applied to the PMSM block s stator windings. The load torque applied to the machine s shaft is first set to 0 and steps to its nominal value (11 N.m) at t = 0.1 s.
Two control loops are used. The inner loop synchronises the inverter gates signals with the electromotive forces. The outer loop controls the motor s speed by varying the DC bus voltage.
