Abstract
In this paper, we propose a multiaccess scheme based on OFDM/Orthogonal-CDMA/Sectored Antenna for the last mile LMDS applications. Power control is adopted on both uplink and downlink. Compared to TDMA/FDMA systems [1], the proposed configuration has a higher capacity and it offers a simpler multiaccess scheme. It is more robust against multipath effects and makes it possible to increase the service coverage. Since only a single carrier frequency will be used at 28GHz, the hardware cost will be lower than that for TDMA / FDMA systems.
