Abstract

This paper deals with the analysis the relationship of uplink and downlink multi-user MIMO systems. We mainly consider the transmit strategies of DPC, ZF-DPC, ZFBF. The uplink and downlink channel are multi-access channel (MAC) and broadcast channel (BC) in our analysis, respectively. According to channel state information, we present the power relationship of MAC and BC in this paper. Thus, based on the relationship, the power allocation schemes of MAC and BC can transformed from one to the other.
