Abstract

In this paper, a new non-uniform channel assignment (NUCA) scheme is presented which is designed for the distinct features of non line-of-sight Fixed - Broadband Wireless Access (F-BWA) networks. Compared to conventional frequency planning, NUCA follows a non-uniform re-use methodology, where for the same re-use factor, the portion of channels is assigned twice in a cluster and none in the subsequent cluster. NUCA presents a different re-use distance configuration among co-channel cells in order to exploit further the concept of access point and customer terminal antenna directivity to reduce the co-channel interference. Simulation results show that NUCA achieves 5 dB improvement for 0.1 interference outage probability when compared to interleaved and rotated channel assignment schemes. Furthermore, the improved performance of NUCA is maintained when polarization assignment is considered, and for different network configurations.
