gold_pn.m

3种pn序列的产生代码

function gold_seq=gold_pn() %cm.m 会用到
connections1=[0 0 0 0 1 0 0 0 1];%产生GOLD序列,[0 0 1 0 1],[1 0 1 1 1],
connections2=[0 0 0 0 1 1 0 1 1];%  [0 0 0 0 0 1 1],[0 0 0 1 0 0 1]
sequence1=m_sequence(connections1);
sequence2=m_sequence(connections2);
L=2^length(connections1)-1;
for shift_amount=0:L-1
    temp=[sequence2(shift_amount+1:L) sequence2(1:shift_amount)];
    gold_seq(shift_amount+1,:)=mod(sequence1+temp,2);%-floor((sequence1+temp)./2).*2;
    echo off;
end;
for i=1:L
    c1(i,:)=2*gold_seq(i,:)-1;
end;
