Abstract :
A model for predicting downlink outage due to cochannel interference in cellular radio systems is presented. The model accounts for path loss, shadowing, and Rayleigh fading. The effects of cell sectoring, power control, and hand-offs are discussed. Particular results are obtained for a cellular system that uses QDPSK with Reed-Solomon coding. Computation of the outage is described. Outage control techniques are discussed, and the impact of Reed-Solomon coding on spectral efficiency is evaluated
