Abstract

In this paper, we analyze the spectral efficiency and outage probability of random unitary beamforming with adaptive modulation(RUBAM) in multi-user MIMO systems. While achievable sum-rate is meaningful from the view point of information theory, the spectral efficiency is more preferable in terms of practical implementation since practical systems do not allow the continuous level modulations. With the help of the exact statistics, we derive the analytical expression of the spectral efficiency and outage probability of RUBAM. Based on your analytical results our proposed RUBAM can be used in designing the practical RUB based MU-MIMO systems.
