自己编写的uwb信道估计

function [MPostion,signP] = EstChannelS(PowEstErr,imp_response, MPnum)

 if PowEstErr == 0
     temp = imp_response;%
 else
    temp = imp_response +  random('norm',0,sqrt(PowEstErr),1,length(imp_response));%
end

for m = 1 : MPnum
    MPostion(m) = find( abs(temp) == max(abs(temp)) );
    signP(m) = temp(MPostion(m));
    temp(MPostion(m)) = 0;
end
