English abstract:
We consider downlink multi-user MIMO transmission based
on block-diagonalization precoding with quantized channel
state information at the transmitter, obtained through limited
feedback. We assume that users are equipped with excess
receive antennas, i.e., the number of receive antennas is larger
than the number of data streams per user, and propose a novel
receive antenna combining method that maximizes the expected
achievable user rate. By means of simulations, we validate
our assumptions and demonstrate significant rate gains
compared to existing combiners of similar complexity.
