代码说明：

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.)

Matlab 向量绘图工具，可应用于向量计算模拟，地图绘制，标尺选定。(This function is a substitute for the standard versions of quiver and quiverm available using a vanilla release of matlab. This version assumes a 2D vector field is being plotted using a gridded flow field from a numerical model. It is primarily intended for Earth System Model analysis. The function enables the scaling of vectors according to a reference vector plotted in the lower right hand corner of the plot axes. The function works for both map and Cartesian axes and allows the color of vectors to be changed. If a reference value is not provided, the reference value is calculated by rounding the median or maximum magnitude of the quiver vectors. Scaling of vectors still occurs even if the reference vector plotting is switched off. This enables different subplots to share identical scaling so that the relative magnitude of vectors can be compared between subplots (provided they share the same grid). The function also includes the ability to plot color vectors, all of equal )
