Abstract :
A novel method for the evaluation of the overall outage probability in cellular mobile radio is proposed. This method involves both links, i.e., M→B (mobile-to-base) and B→M (base-to-mobile), taking into account the joint effects of co-channel and adjacent channel interferences, the net filter discrimination, the radiation patterns of the base station antennas, the power control characteristic, the traffic distribution, and some typical propagation phenomena of the mobile radio environment, such as shadowing effects. The overall outage probability is assessed for some coverages of practical interest for a pan-European cellular TDMA (time division multiple access) digital land mobile radio system currently under study. Cellular coverages with centrally located omnidirectional antennas and with sectoral antennas are considered. For each coverage, frequency plans avoiding strong adjacent channel interferences are presented. The results are given in terms of cumulative distributions of the overall outage probability
