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...
In this paper, the downlink capacity of distributed antenna systems (DAS) with random antenna layout is investigated. When the channel state information is only available at the receiver (CSIR), a good approximation of the downlink capacity is derived by adopting random matrix theory. We also propose an iterative method to calculate the unknown parameters in the approximation. The validity of our...
This paper investigates optimal transmission of space-time block codes (STBCs) in distributed multiple-input multiple-output (D-MIMO) Rayleigh fading channels. The optimal diversity performance is achieved through transmit power allocation implemented at the receiver based on transmit and receive correlations to minimize the average symbol error rate (SER). Evaluation of SER performance of uncoded...
