ahanm.m

包含三种跳频序列编码的实现

function AC=AHanm(A)
% AHanming is the auto correction of A
%tau is the delate time 
% 计算序列A的汉明自相关值，及平均值,延时为tau
Q=length(A);
B=zeros(Q,0);
Hanm=zeros(1,(Q-1));
for tau=1:(Q-1)
    for N=1:Q
        if N>tau
            B(N)=A(N-tau);
        else
            B(N)=A(Q-tau+N);
        end
        B;
        if A(N)==B(N)
            Hanm(tau)= Hanm(tau)+1;
        end
    end
    tau;Hanm(tau);
end
Hanm ;                         %输出的延迟时刻是tau的序列的自相关值，tau=0,1,2,...,Q
AC=mean(Hanm);
