Abstract

We present an assessment of the spectral efficiency of spatial division multiple access systems. Our analysis attempts to incorporate the effects of co-channel interference (CCI) for users sharing the same channel within a cell (intra-cell interference) as well as the CCI from other cells (inter-cell interference). To determine the outage probability we utilize exact results for combined Rayleigh and log-normal shadowing in conjunction with a generic antenna pattern. Results are provided for the outage probability and spectral efficiency for various traffic loads and reuse distances
