function rx=MRC_combine(Tao,Atten,rt,Tf,Ts,N_bit)
%Tao--------path delays
%Atten------path attenuations
%rt---------received multipath signal
%N_bit------the number of symbols
%Tf---------frame duation
%Ts---------sample period
%Dg----pulse duation
%St---------local reference pulse
%算法是先将多径对齐合并，再相关接收
n_path=length(Tao);%the number of multipath
Total_samples=N_bit*(Tf/Ts);%the number of samples in the overall symbols
com_wei=Atten./sum(Atten.*Atten);%the weigth values to be combined 
for i=1:n_path
    rx(i,:)=com_wei(i)*rt(round(Tao(i)/Ts):(Total_samples-1)+round(Tao(i)/Ts));%对接收信号的延时进行处理
end
%多径合并
if n_path>1
    rx=sum(rx);
else
    rx=rx;
end
