Power-Control-Based Band Allocation in Multiband CDMA: Multiband CDMA is useful for constructing DS-CDMA CDMA systems over a non-contiguous spectrum. The method by which users are assigned to their respective frequency bands, termed 'band allocation', is an important part of assuring good performance in multiband CDMA systems. This paper proposes a novel approach to band allocation based...; Tags: CDMA, Allocation, Multiband CDMA; White papers
