Velocity adaptive handoff algorithms for microcellular systems

摘要

Fast velocity adaptive handoff algorithms for microcellularnsystems capable of providing consistent and near optimal performance arenpresented and characterized. Guidelines are first developed for thenamount of spatial averaging required for local mean estimation innmicrocellular systems. Afterwards, three different velocity estimatorsnare introduced and compared with respect to their sensitivity to Ricenfactors, non-isotropic scattering, additive Gaussian noise, andnperformance in a adaptive handoff algorithm
