信道均衡中确定equalizer delay的大小

1. 基本概念

 2. 例题说明

估计信道系数 ：

3. Matlab代码计算

% 创建矩阵 H
h1 = 0.375+1i*0.375;
h2 = -0.125-1i*0.125;
H = [h1 0 0;h2 h1 0; 0 h2 h1;0 0 h2];  % 从h构建的Tepolitz矩阵

% 计算 Square Error
J_n_d_wo_e_nd = H*inv(ctranspose(H)*H)*ctranspose(H);
J_n_d_wo_e_nd = J_n_d_wo_e_nd - ones(4,4)

% 判断n_d
e_nd_1 = [0;1;0;0];
J_n_d_with_e_nd = J_n_d_wo_e_nd * e_nd_1
J_1 = (norm(J_n_d_with_e_nd))^2
