This paper proposes and investigates an optimal resource allocation scheme in the downlink multiuser distributed antenna system (DAS), which is one of the promising systems to provide high data rate in wireless communications. Compared with the conventional cellular system, the resource allocation in the multiuser DAS must consider the conditions of multiple channels between multiple remote antenna...
The distributed antenna system (DAS) is a promising system to provide high data rate transmissions in wireless communications. So far, most researches in the performance analysis for the DAS have been focused on single-user cases. This paper aims to investigate and present an optimal resource allocation scheme in downlink multiuser DASs. Different from the resource allocation in a conventional cellular...
In this paper, we propose a low complexity heuristic algorithm for radio resource allocation in orthogonal frequency division multiple access (OFDMA) systems based on subcarrier channel distribution information (CDI). We consider practical rate adaptation in which rate is adapted using a predefined set of modulation levels, which is in contrast to previous works that consider continuous rate. We formulate...
