Optimizing the DVB-H Time Interleaving Scheme on the Link Layer for High Quality Mobile Broadcasting Reception

The DVB-H technology (digital video broadcasting - handheld) extends mobile connectivity of handheld terminals, specifically offering mobile television and other broadcasting services to small portable devices. This paper presents a performance analysis and a proposal for a parameter optimization of the time interleaving scheme included in the DVB-H forward error correction. Various sets of parameters are studied and optimized with respect to the link performance. An enhanced time interleaving scheme is proposed and evaluated. The channel characteristics used for the analysis correspond to typical mobile usage scenarios which are challenging for the forward error correction.
