BD_GMD_THP_v11_meanpower_user_order_stream_reduct

BD-GMD-THP is a good precoding algorithm for MU-MIMO! The rusult is perfect!

function  [QRP] =BD_GMD_5_stream（HUserNumUserAntennaNumstream_numflag） 

% H 为信道 Nr*Nt
% H 按行分成Num个字h对应每个用户，UserAntennaNum为向量，对应每用户的天线数
% flag标示是 真二用户 1 假二用户 0 主要为了减少计算量



%将H分成各子信道矩阵
[mn]=size（H）;
I=eye（n）;
%Q_end=[];
%R_end=zeros（m）;
%P_end=[];

if UserNum~=2
    
    [Q1R1P1] = BD_GMD_5_stream（H2[UserAntennaNum（1） sum（UserAntennaNum（2:end））][stream_num（1） sum（stream_num（2:end））]0）;%假二用户
    H2=H（UserAntennaNum（1）+1:end:）;
%    rank_of_rightmatrix=rank（（I-P（:1:stream_num（1））*P（:1:stream_num（1））‘））;
%    rank_of_old_H=rank（H（UserAntennaNum（1）+1:end:））;   
%    rank_of_new_H=rank（H2）;
    [Q2R2P2] = BD_GMD_5_stream（H2*（I-P1*P1‘）UserNum-1UserAntennaNum（2:end）stream_num（2:end）1）;
 
%    合成最后分解矩阵
    Q=blkdiag（Q1Q2）;
    R=blkdiag（R1R2）;
