直方图均衡化，数字图像处理，简单matlab函数(Histogram equalization, digital image processing, a simple matlab function)

Orthogonal Frequency Division Multiplexing (OFDM) is a spectrally efficient multicarrier modulation technique for high speed data transmission over multipath fading channels. High Peak-to-Average Power Ratio (PAPR), which leads to power inefficiency in the RF portion of the transmitter, is a major drawback of OFDM.

实现基于BPSK的直接扩频信号调制，并显示出各阶段信号波形。(Direct-based BPSK modulated spread spectrum signal, and shows the signal waveform of each phase.)

三相并联型有源电力滤波器 基于瞬时无功理论 未对直流侧电压进行控制(Three-phase APF for power quality improvement)

正交频分复用(OFDM)是第四代移动通信的核心技术,它是实现多媒体业务发展的基础.讨论了如何利用Simulink进行OFDM系统仿真,并给出了具体的仿真模型.利用仿真模型得到OFDM差错性能分析结果,通过对结果的分析,提出了改善性能的方法. (Orthogonal frequency division multiplexing (OFDM) is the core of the fourth generation mobile communication technology, it is the basis for the development of multimedia services. Discusses how to use Simulink for OFDM system simulation, and given the specific simulation model. Using the simulation model OFDM Error Performance Analysis of the results obtained through analysis of the results, proposed to improve performance.)
