selectantenna2.m

基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.

function [H_comb,H_LA,ps]=selectAntenna2(H,N,subN,state,T_div)
if state == 5 || state == 7
    H1 = squeeze(H(:,1,:));
    g = abs(H1).^2;
    for k=1:floor(N/subN)
        g_subN(k,:)=mean(g((k-1)*subN+1:k*subN,:),1);
    end
    for tx = 1:T_div
        g_tp(:,tx) = sum(g_subN(:,tx:T_div:end),2);
    end
    [temp,ps]=max(g_tp,[],2);
    %H_old = H(:,DELAY+1:end,:);
    for k = 1:floor(N/subN)
        H_comb((k-1)*subN+1:k*subN,:,:) = H((k-1)*subN+1:k*subN,:,ps(k):T_div:end);
        H_LA((k-1)*subN+1:k*subN,:) = squeeze(H((k-1)*subN+1:k*subN,1,ps(k):T_div:end));
    end

    H_comb = H; ps = [];
