Performance analysis of time slicing in DVB-H

Abstract

Digital Video Broadcasting for Handhelds (DVB-H) is the latest DVB standard from the DVB Group targeting handheld, battery powered devices such as mobile telephones, PDAs(Personal Digital Assistants). etc. DVB-H enables IP data services including low definition TV services to be received on battery powered handheld terminals. Time Division Multiplexing (TOM, is the technology that is usually used in computer and telecommunication systems for resoursce allocation. Time slicing is based on TDM and is one of the characteristics of DVB-H. This paper presents a basic model for predicting the power saving achieved by the time slicing algorithm used in DVB-H followed by analysis of the performance of the algorithm based on simulations using Matlab and Opnet; The simulations required the writing of Matlab and Opnet code to model the effect of time slicing. The model and simulations presented illustrate the significant power savings that can be achieved by time slicing.
