Abstract

This paper addresses the capacity of the B-CDMA macrocellular overlay system. The B-CDMA overlay method enables cellular systems to provide wireless high speed communications. The novelty in this paper is the introduction of a new CDMA blocking model to calculate the capacity of the B-CDMA Overlay System under various AMPS and B-CDMA traffic intensities. Forward and reverse link capacities are both calculated. We show that a B-CDMA overlay can accommodate 10-22 times more users than the existing FDMA system. These results are obtained by incorporating the effects of implementation loss, APC inaccuracy due to multipath fading and spillover. Simulation results are included.
