自由空间光通信系统在大气湍流信道下的3个主要性能指标分析，即平均误码率、中断概率和平均信道容量。其中大气湍流采用gamma-gamma湍流信道衰退模型。3个M文件为平均误码率与平均信噪比之间的关系(BER_SNR.m)，中断概率(OutageP.m)，以及平均信道容量与平均信噪比之间的关系（C_SNR.m）。程序可直接运行。(The analysis of 3 key performance indicators of Free-Space Optical communication system in atmospheric turbulent channel, namely the average bit error rate, outage probability and the average channel capacity. The atmospheric turbulence is modeled by the gamma-gamma turbulent channel fading model. Three M-files are the relationship between the average bit error rate and the the average SNR (BER_SNR.m), outage probability (OutageP.m), the relationship between the average channel capacity and the average SNR (C_SNR.m).The programs can run directly.)

说明：  新独立分量分析的算法，主要用于盲信号的分离计算(The newly independent component analysis algorithms, mainly for blind signal separation of the calculation)

研一上学期，学校开了数值分析这门课，而且要求用matlab进行上机试验，经过一段时间的学习，对matlab有了最初步的了解，结合所学课程，废了好大的劲才编了几个小程序，希望对后来学习的人有点帮助。(Kenichi last semester, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, after a period of learning, of matlab with the most basic understanding, combined with the course, the repeal of several large series劲才a few small programs, and they hope to learn a little bit later to help.)

可以对卡尔曼滤波有较为准确的认识与理解，并且对迭代算法有一定的了解。 (Can to kalman filter have relatively accurate knowledge and understanding, and to have some understanding of iterative algorithm.)

一般的esprit算法好的时间比较大，在计算子空间是算法比较烦，我改了一些矩阵算法。(general esprit algorithm good time, the calculation algorithm is a subspace trouble, I changed some matrix algorithm.)

用模拟退火求解非线性规划的具体例子，很有提高，希望大家能学习学习(Nonlinear programming using simulated annealing)
