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.)

基于matlab GUI的一个简单计算机系统，能实现加减乘除等简单算法(A simple matlab GUI based computer system, to achieve a simple algorithm for addition, subtraction, etc.)

说明：  matlab编程密度聚类dbscan算法，本密度聚类算法dbscan是基于周志华老师《机器学习》介绍编程的，经检验效率较高(Matlab programming density clustering dbscan algorithm. The density clustering algorithm dbscan is based on the introduction of "Machine Learning" by Teacher Zhihua Zhou.)

说明：  常规OFDM系统容易导致ICI，为了消除ICI，在信号传输前进行编码，本系统为1/2PCC编码，提高系统效率。(Conventional OFDM system easily lead to ICI, is encoded in the signal before transmission, in order to eliminate ICI, this system for 1/2PCC encoding to improve system efficiency.)

高效紧凑的高频地波雷达天线阵列设计 ( Efficient and compact HF radar antenna array design)

DC dynamic braking is obtained when the stator of an induction motor running at a speed is connected to a dc supply.dc current flowing through the stator produces a stationary magnetic field.Motion of rotor in this field induces voltage in the rotor winding.Machine therefore works as a generator.Generated energy is dissipated in the rotor circuit resistance,thus giving dynamic braking.
