以ofdm作为调制方式的发送端的信道模型(To ofdm transmitter as modulation of the channel model)

Add Gaussian white noise (mean=0 and variance=0.05 ) to the image using imnoise command. Now use fftshift command to put all zero frequencies in the middle. Low-pass filter this function by applying a mask saving only the central Fourier coefficients. Set the mask width to 255 and create the filtered image.

information.m用来计算两个一维向量x和y的互信息。把压缩包中两个程序放在一起就可以运行(information.m used to calculate the two one-dimensional vectors x and y of the mutual information. The compressed package of two programs can run together)

基于MRAS无速度传感器的永磁同步电机的仿真模型，可以实现较好的仿真结果。(MRAS based speed sensorless permanent magnet synchronous motor simulation model, can achieve a better simulation results.)

we investigate a new blind adaptive fractionally-spaced TEQ (FS-TEQ) for multicarrier systems in order to reduce efficiently intersymbol interference. We also exploit the cyclic prefix and fractionally-spaced TEQ to create a blind adaptive globally convergent channel-shortening algorithm.
