说明：  BPSK原理仿真，采用的是相干解调和非相干解调(BPSK principle simulation, using coherent detection and non-coherent demodulation)

说明：  利用matlab软件完成OFDM应用在数字水印的应用研究(OFDM using matlab software applications to complete the application in digital watermarking)

It is a single phase half controlled inverter.

最大功率输出控制的光伏发电系统，通过输出功率作为反馈信号控制输入电压，是系统处于最大功率输出。这个是最大功率追踪部分。(Maximum power output of photovoltaic power generation system controlled by the output power control input voltage as a feedback signal, the system at the maximum power output. This is the maximum power point tracking section.)

说明：  这是一个matlab 的GUI，matlab的版本可在7.0(matlab GUI)

lfm信号的处理，lfm信号的处理的matlab仿真(lfm signal processing)

移动通信mimo信道建模中用到的小程序3。(Used in mobile communication mimo channel modeling program.)

新的微粒群算法 利用matlab实现 简单(a new PSO)

matlab数字水印 通过这个程序可以给原图象加上水印 但不可以提取！(a watermark sourcecode implemented by MATLAB. By using this program, primary image can be embedded while the watermark cannot be extracted.)
