USE OF BASE STATION ANTENNA DIVERSITY FOR MOBILE SPEED ESTIMATION

Knowledge of the speeds of mobiles in a radio environment isa valuable input parameter to an intelligent mobility management system for pred icting handover occurrences, etc. A previously published paper reporte d an analysis and experimental results in the use of diversity techniq ues for the determination of the speed of a mobile in a nonstationary Rayleigh environment. In the Letter, the work is extended through a di fferent approach and it is shown through various examples that the met hod has limitations.
