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