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)

quick-acquisitionmethod-of-signals
主要研究了两种高动态扩频信号快速捕获的方法,即基于FFT 的频域(载波) 并行捕获法和基于FFT 的时域(伪码)
并行捕获法,并使用MATLAB 进行了仿真和比较。仿真结果表明:基于FFT 的频域并行捕获可捕获较大的频偏并跟踪一定
的频率变化率,可用于卫星变轨等高动态、高加速度等飞行过程。而基于FFT 的时域并行捕获可快速捕获码相位,用于在轨飞行的飞行器,可根据轨道参数提前预报其多普勒频偏,但同时需要精密测距的飞行过程。(Research on the quick acquisition method of the high dynamic spread spectrum signals)
