| Abstract | For MISO multi-users downlink wireless communication system with precoding at the transmission, it is important to decrease the feedback rate. In this paper, we study different algorithms and criterions in order to significantly reduced the amount of feedback data. We associate the classical norm criterion with a criterion based on the users orthogonality. Without cooperation between the users, we only allow users that are orthogonal with the others to feedback their channel information to the base station. We calculate the theoretical thresholds and finally we evaluate the performance of the different criterions using numerical simulation. |
