802.11 SIMULATION REPORT AND SOURCE CODE

依据两个点的经纬度计算这两点在地球上距离的函数文件，误差很小(Calculated based on latitude and longitude of two points on Earth from these two points in the function file, the error is small)

说明：  改进后的BP神经网络，可以用于模型的优化和预测(The improved BP neural network can be used for optimization and prediction models)

粒子群算法,自己编的一个程序，可以实现，运行main函数(Particle Swarm Optimization)

采用geese算法对采样的阵列信号进行处理，根据阵列结构上存在的差异进行估计，采用标准差的方式进行估计。geese算法性能的好坏 (Geese algorithm on sampled array signal processing, according to an estimate of the differences that exist on the array structure, estimated using standard differential manner. the geese algorithm performance quality)

说明：  this is simple signal processing matlab code

matlab下实现模拟退火算法的程序，非常好非常实用的程序！(matlab simulated annealing algorithm under the procedures, a very good program very useful!)

matlab程序，读取txt文件中的波形数据，并画图显示。(matlab program, read the txt file in the waveform data, and drawing show.)

说明：  本文对指纹特征点的提取，特征点的匹配，用matlab进行了实现(In this paper, the fingerprint feature points extraction, feature point matching, was realized with matlab)

采用FSK调制方式，用于仿真高斯噪声、单音干扰等多种干扰环境下跳频系统性能及误码率(FSK modulation, frequency hopping system performance and bit error rate for the simulation of Gaussian noise, single tone jamming and other interference environment)
