摘要
Classical antenna selection schemes require instantaneous channel stateinformation (CSI). This leads to high signaling overhead in the system. Thiswork proposes a novel joint receive antenna selection and precoding scheme formultiuser multiple-input multiple-output uplink transmission that relies onlyon the long-term statistics of the CSI. The proposed scheme designs theswitching network and the uplink precoders, such that the expected throughputof the system in the long term is maximized. Invoking results from the randommatrix theory, we derive a closed-form expression for the expected throughputof the system. We then develop a tractable iterative algorithm to tackle thethroughput maximization problem, capitalizing on the alternating optimizationand majorization-maximization (MM) techniques. Numerical results substantiatethe efficiency of the proposed approach and its superior performance ascompared with the baseline.
