信号检测贝叶斯
使用Matlab编程,对教材74页例3.3.1进行编程仿真。其中,正电压A的值、噪声方差值、每个码元周期内的采样点数N自行设定(可设置为可调的变量)。噪声值可使用Matlab中产生高斯随机数的函数来进行仿真。贝叶斯检测判决式中,先验概率P(H1)=P(H0),判断错误的代价因子设为1,判断正确的代价因子设为0.
按照上述参数的设定进行仿真,实现对仿真数据的贝叶斯检测判决;循环生成仿真数据,并进行判决结果的统计,即记录判决正确的次数,估计正确判决的概率。(The use of Matlab programming, teaching materials 74 pages of 3.3.1 programming simulation. Among them, the value of positive voltage A, the variance of noise, the number of sampling points in each symbol cycle (N) can be set by itself (adjustable variable). Noise values can be simulated using the function of generating Gauss random numbers in Matlab. In the Bias detection decision, the prior probability P (H1) =P (H0), the factor of error judgment is set to 1, and the correct cost factor is set to 0.
According to the simulation parameters and realize the judgment of Bayesian detection simulation data; generating cycle simulation data, statistics and decision, which records the correct number of judgment, the estimated probability of correct decision.)

实验一
说明: 一般信道容量迭代算法
(1)初始化信源分布:P^((0))=(p_(1 ),p_(2 ),…,p_(i ),…,p_r),置迭代计数器k=0,设信道容量相对误差门限为δ,δ>0,可设C(0)=-∞;
(2)φ_ji^((k))=(p_ij p_i^((k)))/(∑p_ij p_i^((k)) ) i=1,…,r;j=1,…,s;
(3)p_i^((k+1) )=exp?[∑_j?〖p_ij lnφ_ji^((k)) 〗]/(∑_i?〖{exp?[∑_j?〖p_ij lnφ_ji^((k)) 〗]}〗) i=1,…,r;
(4)C^((k+1))=ln∑_i?〖{exp?[∑_j?〖p_ij lnφ_ji^((k)) 〗]}〗;
(5)如果,
(|C^((k+1) )-C^((k)) |)/C^((k+1)) ≤δ,
转向(7);
(6)否则,置迭代符合 k+1→k,转向(2);
(7)输出p_i^((k+1) )和C^((k+1));
(8)停止。(General channel capacity iterative algorithm)
