Estimation of reverse-link capacity for multiband DS-CDMA systems

ABSTRACT

In the future deployment of wideband DS-CDMA mobile communication systems, spectrum overlay among sub-bands with different bandwidths is probably inevitable. In this paper we present an approach to estimate the reverse-link capacity of overlaid multiband DS-CDMA systems in terms of the maximum number of users in each sub-band. We will derive the general capacity formula, and present a decomposition method for the capacity analysis to reduce the computational complexity. Based on this decomposition method the conditions for maximum bandwidth utilization are obtained. These results are then extended to account for imperfect power control cases.
