Abstract

In this paper a joint design of linear pre-coders and equalizers is investigated for the uplink in multiuser distributed antenna system (DAS) over uncorrelated channels with perfect channel state information (CSI) at both the transmitters and receivers. By minimizing the sum mean square error (MSE) of all users, under a total power constraint, the linear transceiver design is modeled as an optimization problem. Based on the research on centralized multiple input multiple output (MIMO) antenna system (CAS), the optimal solution of the problem is found. Through the simulation of the average SER, it is concluded that optimal design of pre-coders and equalizers in DAS outperforms that in CAS.
