In this study, the author presents performance analysis of a zero-forcing (ZF)-precoded scheduling system with adaptive modulation for multiuser-multiple input multiple output transmission. The proposed scheduling system adapts the transmission rate and selects the best modulation to satisfy a given target bit error rate (BER). The author derive the tight closed-form expressions of the ZF-precoded...
In this paper, we propose a novel joint diversity with multi-stream selection for error-rate minimization in multi-user spatial multiplexing systems with BD-precoding. The proposed scheme adaptively selects the user set, the transmit antenna subset and the number of multi-streams maximizing selection criterion. For complexity reduction, we employ the SNR-based selection criterion. The joint diversity...
