Abstract
In this paper, we suggest applying multicarrier spread spectrum (MC-SS) techniques to fixed wireless access applications. Due to the fixed nature of subscribers in these applications, cross-polarization discrimination and directional subscriber antennas can be used to reduce interference in a multicellular system. Power control schemes are applied on both uplink and downlink. The suggested system has a high capacity and uses a simple multiaccess layer. It is robust against multipath effects and can provide service coverage not only to line-of-sight (LOS) but also to nearly LOS subscribers. Only a single carrier frequency is used in the entire network.
