This paper presents a handover performance analysis suitable for implementation in TDD-CDMA cellular network. Firstly, RSCP (received signal code power)-triggered and SIR (signal to interference ratio)-triggered hard handover measurement criteria for TDD-CDMA are analyzed theoretically and their performances are compared by simulations. Secondly, the handover parameter T_margin, which is defined as the margin of measurement value used in adding/dropping users to/from active set or full candidate set to avoid ping-pong effect, is carefully set and addressed. Thirdly, the optimum value of measurement reporting period is investigated. Finally, the influence of measurement error is described. As outcome of these analysis and simulations, some simulation results are illustrated and the conclusion is drawn that SIR-triggered scheme is more available to make measurement criteria. Simulations are carried out in a hexagonal macro cellular network with a dynamic system level simulator.
