In this paper, the uplink of a multi-user distributed antenna system (DAS) with antenna elements deployed on a circle is investigated. We address the problem of calculating the sum-rate capacity with per-user power constraints. Based on system scale-up, we derive a good approximation of the sum-rate capacity by adopting random matrix theory. We also propose an iterative method to calculate the unknown...
In this paper, the uplink of a multi-user distributed antenna system (DAS) with antennas deployed on a circle is investigated. The optimal radius to deploy antennas is studied with the target of sum capacity maximization. Adopting random matrix theory, a good approximation of the per-user sum capacity is derived. We also present a numerical method to calculate the unknown parameters in the approximation...
