STBC（空时编码）的编码和解码方法

function symbol_stbc=STBC_coding(symbol)
[L,long,Nt]=size(symbol);
symbol_stbc=zeros(L,long*2,Nt);
for k=1:long
    temp1=symbol(:,k,1);
    temp2=symbol(:,k,2);
    symbol_stbc(:,2*k-1,1)=temp1;
    symbol_stbc(:,2*k,1)=-conj(temp2);
    symbol_stbc(:,2*k-1,2)=temp2;
    symbol_stbc(:,2*k,2)=conj(temp1);
end
