说明：  专家场做图像的去噪和修复，老外写的，很不错。(Experts to do field image denoising and restoration, written by a foreigner, is pretty good.)

中国地图gis文件,包括全国省市区域和河流山脉(Chinese map of arcgis)

说明：  OFDM多径信道的仿真和模拟,有效的仿真了多径信道(simulation of OFDM through multipath channel)

TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)

说明：  纯追踪轨迹跟随算法，采用matlab实现。(The pure tracking track following algorithm is realized by MATLAB.)

说明：  扩展卡尔曼滤波，适用于多目标跟踪，里面还有一个子程序(Extended Kalman Filter)

ORL-人脸库的pca算法程序。可以测试其人脸识别的时间和准确率(ORL-Face PCA algorithm library procedures. To test its face recognition time and accuracy rate)

在Matlab环境下用于计算CRC16的代码，本原多项式为X16+X15+X2+1，并提供测试文件。(In the Matlab environment for the calculation of CRC16 code, the primitive polynomial is X16+X15+X2+1, and provide the test file.)

混沌通信的源代码，很有参考价值的！关于卡尔曼滤波等实现FM-DCSK通信系统性能仿真(Chaotic communication source code, a good reference! On Kalman filtering to achieve FM-DCSK Communication System Performance Simulation)

说明：  RSSI室内定位中的最小二乘法定位，效果挺不错的(The least square method in RSSI indoor positioning has a good effect)
