Abstract :
The paper considers precoder design for the downlink of multi-user MIMO systems where antenna array are used at both the base station and the mobile receiver. The proposed precoder does not completely eliminate multi-user interference (MUI) as previous schemes with multiple receive antennas per user, but obtains an optimum compromise between noise enhancement and MUI mitigation. Furthermore, by extracting diversity from each user´s subspace and reducing precoding loss, the proposed scheme can offer a significant gain in term of average bit error rate (BER).
