3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与理想信道(没有多径)作比较。 需要的支撑子程序为qpsk_berest.m,vxcorr.m,random_binary.m.(Three fixed-path multipath AWGN channel QPSK system BER performance simulation, and with the ideal channel (no multipath) for comparison. Need the support of subprogram for qpsk_berest.m, vxcorr.m, random_binary.m.)

滑模变结构仿真，malab源程序。滑模变结构控制算法简单、鲁棒性好和可靠性高，故被广泛应用于运动控制中，尤其被用于可建立精确数学模型的确定性控制系统中(SMVSC simulation, malab source. Sliding mode variable structure control algorithm is simple, good robustness and high reliability, it is widely used in motion control, especially be used to establish a precise mathematical model can be deterministic control system)

说明：  GA算法代码 function pop=initpop(popsize,chromlength) pop=round(rand(popsize,chromlength)) rand 随机产生每个单元为 {0,1} 行数为 popsize，列数为 chromlength 的矩阵， roud 对矩阵的每个单元进行圆整。这样产生的初始种群。 2.2 计算目标函数值 2.2.1 将二进制数转化为十进制数(1) 遗传算法子程序 Name: decodebinary.m 产生 [2^n 2^(n-1) ... 1] 的行向量，然后求和，将二进制转化为十进制(GA algorithm code function pop=initpop(popsize,chromlength) pop=round(rand(popsize,chromlength)) rand 随机产生每个单元为 {0,1} 行数为 popsize，列数为 chromlength 的矩阵， roud 对矩阵的每个单元进行圆整。这样产生的初始种群。 2.2 计算目标函数值 2.2.1 将二进制数转化为十进制数(1) 遗传算法子程序 Name: decodebinary.m 产生 [2^n 2^(n-1) ... 1] 的行向量，然后求和，将二进制转化为十进制)

计算成组滑动的滑窗检测器的最佳门限已知: 击中数N = 128, 组宽n = 8，PF = 10¡ 6，PD = 90 假设以下条件: (a) 信号不起伏 (b) 忽略天线波束调制 1 (c) 计算PD时忽略目标区以外噪声的影响 组门限(第二门限)为K=8 滑窗的门限(第三门限)为L=16 (滑窗中包含的组数为16) 求解: 最佳的KOPT 和LOPT，对这题做了具体仿真实现。需要的朋友，一定知道很有用。(Optimal threshold calculated as group slidable window detector is known: hit number N = 128, the group width n = 8, PF = 106, PD = 90 assuming the following conditions: (a) signal is not undulation ( b) ignore the antenna beam modulation 1 (c) the calculation of PD ignored outside the target area noise of impact group door limit (the second door limit) for K = 8 sliding window of the door limit (third door limit) for L = 16 (sliding window contains group 16) to solve: the best of the KOPT the LOPT, these questions do specific simulation to achieve. A friend in need, we must know to be useful.)
