Research Of Interference And Coexistence Of TD-SCDMA And TD-LTE

This paper presents adjacent interference performance analysis between two communication system, TD-SCDMA and TD-LTE. Certainty analysis method and Monte Carlo simulation method are adopted to evaluate performance of these co-existence systems.Adjacent interference is first/roughly evaluated by certainty analysis method. And also we give reasonable slot/subframe configuration to acquire synchronization and avoid interference. Then the emphasis is put on system simulation. Simulation takes several steps including designing modeling framework and simulation process, create inter-RAT interference function module, macro-cell simulation of different scenes and analysis based on simulation results. The simulation results of TD-SCDMA and TD-LTE co-existence in this paper provide valuable reference for the research of hybrid network planning and optimizing.
