greedy search for signal processing

说明：  信道极化图解，信道在经过极化后，有的性能接近1，有的接近0，保证正确(Channel polarization diagram: after the channel is polarized, some of the performances are close to 1, some are close to 0, ensuring the correctness)

说明：  MATLAB实现Ovsf扩频解调，WCDMA(MATLAB implementation Ovsf Spread)

function struct example dev - c

it is a very good example for OFDM which has tow CP removal Technic.

在研究了超高速OFDM系统传输模型的基础上，对OFDM系统的传输信号结构进行了分析，结合传统的多普勒频移算法，用OFDM信号循环前缀所包含的相对频偏信息设计了实时性较好的多普勒频移估计方法，并分析了多径效应对于循环前缀数据的“污染”效应，对该算法进行了优化，提高了算法的频移估计性能，并对该算法进行了性能验证。(Based on the study ultra-high-speed transmission of OFDM system model, the OFDM signal structure for the transmission system is analyzed, combined with traditional Doppler shift method, the relative deviation OFDM signal with cyclic prefix information contained in the real-time design Doppler shift better estimation methods, and analyzes the " pollution" effect of multipath effects for cyclic prefix data, the algorithm has been optimized to improve the frequency estimation algorithm performance and the performance of the algorithm verification.)

最大类间方差法的matlab实现，可以对灰度直方图呈现良好的双峰特性的图像进行有效的分割(Otsu method to achieve the matlab can histogram showed bimodal characteristics of a good image for effective segmentation)

关于MATLAB的图像消噪程序，很有用的(MATLAB image denoising procedure, useful)

关于无人动力伞的matlab数学模型建立，以及无人动力伞的控制研究。(unmanned paramotor on the matlab mathematical modeling, and control of unmanned paramotor.)

本程序是基于方向优先权的机器人最优路径寻找算法，也可用于求解迷宫的最短路径。(This procedure is based on the priority direction of the robot to find the optimal path algorithm can also be used to solve the shortest path to the maze.)
