In this paper, the downlink performance of distributed antenna systems (DAS) with random antenna layout is investigated. We consider the composite channel including large-scale fading and small-scale fading. When the large-scale channel state information, which usually varies slowly and is easy to be obtained, is available at the transmitter, the problem of power allocation among distributed antennas...
In this paper, the downlink performance of a distributed antenna system (DAS) with random antenna layout is investigated. We address the problem of characterizing the downlink capacity with the generalized assumptions: (al) per distributed antenna power constraint, (a2) generalized mobile terminals equipped with multiple antennas, (a3) a multi-cell environment. Based on system scale-up, we derive...
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...
