Reverse link capacity analysis for cellular CDMA systems employing combining macrodiversity

Abstract

In the open technical literature, all the papers investigating the reverse link capacity of the combining macrodiversity simplified their analysis by assuming that the radio signals received by all the base stations in the cellular CDMA system are combined to detect mobile users. Therefore, their analysis results are actually an upper bound of the real reverse link capacity. In this paper, by assuming that only the radio signals received by the base stations in the vicinity of the mobile user are combined to detect the mobile user, we have theoretically analyzed the reverse link capacity of cellular CDMA systems employing the combining macrodiversity. Furthermore, by taking a pedestrian application in cdma2000 as an example, computer simulations are performed, and the obtained simulation results have confirmed our theoretical analysis.
