In this paper, the energy efficiency (EE) of distributed antenna system (DAS) with multiple receive antennas is investigated over composite fading channel that takes the path loss, shadow fading and Rayleigh fading into account. Our aim is to maximize EE which is defined as the ratio of the transmission rate to the total consumed power under the constraints of maximum transmit power of each remote...
This paper studies the power allocation (PA) and distributed antenna (DA) selection in the downlink orthogonal frequency division multiplexing distributed antenna systems (OFDM-DAS). Two schemes are analyzed, with the objective of maximizing the downlink received signal power. In the first scheme, the DA selection is based on large-scale fading only and the related PA is simple. It is proved that...
In this paper, we focus on the development of effective and practical scheduling algorithm for heterogeneous services per user of orthogonal frequency division multiplexing distributed antenna systems (OFDM-DAS). We take two scenarios into account: 1)Fixed distributed antenna connection (FDAC), in which each user can connect to only one distributed antenna (DA) port; 2)Dynamic DA connection (DDAC)...
