Incorporating digital repeaters into the soft handover standard in digital video broadcasting for handhelds

Abstract

Digital Video Broadcasting for Handhelds (DVB-H) is a standard for broadcasting IP data to portable devices. This paper proposes and analyses the Repeater-Aided Soft Handover (RA_handover) algorithm for a DVB-H receiver with Multiple Input-Multiple Output (MIMO) antennas and presents the benefits of implementing the RA_handover compared with a handover process without repeaters. Simulation models are developed to analyse the RA_handover approach. It is shown that the RA_handover could greatly improve the quality of service and consume much less front-end battery power than the handover method without repeaters. This paper also provides valuable outcomes for service providers and standard policymakers.

DVB-H Systems: Quality-Based Active Handoff Assisted by UMTS Return Channels

“…The more measurements are made, the highest amount of battery power is consumed and the more remarkable decreasing in the quality of services is observed [12]. Therefore, our proposal objective is to find a way to reduce the handoff measurement frequency and to establish new criteria for triggering handoff decision and execution only when actually necessary.…”
