说明,用twosignal(tau)产生两信号序列,在下面的程序中装载两信号进行处理。
clear
close all;
load time; % load the time sequence
load e_s; % load the emission signal
load r_s; % load the receive signal
t;e_ss;r_ss;
e_signal=e_ss;
r_signal=r_ss;
subplot(311);plot(t,e_signal);grid on;
hold on;plot(t,r_signal);
title('Emission & Return signal');
%% begin of algorithm
% initialization
L=385; % 滤波器阶数
points=length(t); % the simple-points
d=r_ss(1:points)';
X=e_ss(1:points)';
y=zeros(1,points)'; % system output signal
w=zeros(L,1); % 每列代表每次迭代的L个权值,行代迭代次数,第几次
