Abstract

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 analysis is well verified by simulations. The approximation is illustrated to be accurate and the iterative method is verified to be efficient.
