ovsf_generator.m

该程序是用MATLAB编写的应用于WCDMA中扩频的OVSF码的产生

function ovsf_codes=ovsf_generator(spread_factor,code_number)
ovsf_codes=1;
if spread_factor==1
    return;
end
for i=1:1:log2(spread_factor)
      temp=ovsf_codes;
for j=1:1:size(ovsf_codes,1)
   if j==1
       ovsf_codes=[temp(j,:),temp(j,:); temp(j,:),(-1)*temp(j,:)];
    else
        ovsf_codes=[ovsf_codes; temp(j,:),temp(j,:); temp(j,:),(-1)*temp(j,:)];
    end
end
end
if code_number>0
    ovsf_codes=ovsf_codes(code_number,:);
end
end
