| Abstract(in English) | We propose centralized iterative algorithms that jointly determine the optimal transmit and receive filters for a K-user multiple-input multiple-output (MIMO) interference channel (IC). The optimality criterion is based on the achievable sum-rate and the average per user multiplexing gain in the MIMO IC. By allowing channel state information (CSI) exchanged between base stations (BSs) and a central unit (CU), we use a feedback topology where a CU collects local CSIs from all BSs, computes all transmit and receive filters and sends them to corresponding user-BS pairs. Note that the local CSIs at BSs are obtained from the estimation of the channel states during the so-called uplink-training phase. At the CU, we propose iterative algorithms utilizing alternating optimization strategy to design the transmit and receive filters. |
