仿真了OFDM中的SLM方法 ，并附有仿真图形，对于初学PAPR的朋友可有用(Simulation of the OFDM in the SLM method, together with simulation graphics, for a friend can be useful for beginners PAPR)

rake的matlab程序，经典的rake仿真程序(rake in Matlab procedures, the classic rake simulation program)

这是粒子群优化算法用于anteenna阵列综合的通用代码。

On Sunday, April 27, 2003, Fresno will celebrate Earth Day in downtown Fresno at Courthouse Park. The event will begin at noon. This year we will include music, speakers, and vendors, plus activities for children. Fresno Earth Day is recognized as the only Earth Day festival that happens in Fresno, and the largest in the Central Valley. The Fresno Earth Day Committee is a small group of environmental activists hoping to broaden the appeal of a better planet and environment. We are a non-profit organization whose fiscal fiduciary is the Fresno Center for Nonviolence.(On Sunday, April 27, 2003, Fresno will celebrate Earth Day in downtown Fresno at Courthouse Park.

说明：  This code is related to the course Digital Communications. It easily reproduces the error probability as a function of the SNR per bit for QPSK and 16-QAM systems using MATLAB

Parallel Chopper circuit

程序可以提取点云数据的特征点，提取三维散乱点云的边界(Program point cloud data can be extracted feature points extracted boundary of D Scattered Clouds)

王永良等编著的《空时自适应信号处理》是对雷达信号进行空时二维处理的经典教材，值得参考(Wang Yongliang ed space-time adaptive signal processing " is a classic textbook, it is worth the two-dimensional space-time radar signal processing reference)

背景检测,使方法更加的优化了，更容易接受学习，使读者容易接受(background detection)
