OFDMcode
OFDM信号的编码译码仿真,英文说明更详细。(This simulation script set allows for an OFDM transmission to be
simulated. Imagetx.m generates the OFDM signal, saving it as a
windows WAV file. This allows the OFDM signal to be played out a sound
card and recorded back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.
See settings.m for more details.
Note: The both the receiver and transmitter must have a copy of the
input data file, as this is used for calculating the exact number
of data words in the transmission.
The scripts should work as extracted. Just run imagetx.m to generate the
OFDM signal. Then run imagerx.m to decode the signal. The initial settings
transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be
compared with the original data by listening to the two wave files.)

pwminverter_fed_im
This program has been written using Matlab/Simulink software. It can be used to find out the behavior of the induction motor behaviore when fed from a PWM inverter. The program is written so that the user can simulate any induction motor he wants by just loading the electrical and the machanical parameters in the workspace. The induction motor is modelled by the 7th order dq model which takes the iron loss component into account. The motor works in open loop but the closed loop can be easly performed by just adding the vector controller or any other controller and a PI speed controller.

说明: 若非奇异矩阵A能够分解为一个正交矩阵Q与非奇异上三角矩阵R的乘积,即:
A=QR。则称其为A的QR分解。
实现QR分解的方法有很多种,包括Givens变换法,Householder变换法,Schemit正交化法。具体原理可以参考《矩阵论》(程云鹏,西工大出版)教材,这里仅给出三种实现QR分解的程序。(If nonsingular matrix A can be decomposed into a product of orthogonal matrix Q and nonsingular upper triangular matrix R, that is:
A=QR. It is called QR decomposition of A.
There are many methods to realize QR decomposition, including givens transformation, householder transformation, and scheme orthogonalization. The specific principle can refer to the teaching materials of matrix theory (Cheng Yunpeng, published by Xigong University). Here, only three kinds of QR decomposition procedures are given.)
