ABSTRACT
The distributed antenna system (DAS) has emerged as a promising candidate for the future beyond 3G or 4G mobile communications thanks to its open architecture and flexible resource management. The distributed characteristic of the antennas provides a more efficient utilization of space resources; however, it also raises a crucial challenge for the advanced resource allocation. In this chapter, the optimal resource allocation for DAS networks is investigated. We start with an overview of the current adaptive techniques
for wireless systems. The resource allocation strategies in distributed channels are then proposed, and the performance comparison with equal allocation helps us understand why an adaptive resource allocation is indispensable to the DAS. It is further extended to the multi-user scenario and the optimal resource allocation among multiple users is discussed. The chapter concludes by presenting some open research issues in the realization of resource allocation for DAS networks.
