Abstract

Uplink synchronous transmission has been proposed to improve the uplink capacity of DS-CDMA systems by means of canceling interference from the main paths of other intra-cell users. A significant capacity gain has been reported in a single cell environment. This Letter further investigates the uplink capacity in a multiple cell environment, where two crucial factors are taken into account, namely code shortage problem and soft handover. The impacts of the target Eb/Io and the other-to-own cell interference ratio, together with the number of channelisation codes, are discussed mathematically and then, confirmed through system level simulations with more realistic parameters.
