Abstract :
DVB-SH is a new broadcasting standard offering a mobile TV service for handheld devices using hybrid satellite/terrestrial-repeaters solution. A new link layer protection algorithm called Multi-Burst Sliding Encoding (MBSE) has been recently adopted to cope with the long fading time introduced by the direct satellite link. This paper presents a method to optimize the MBSE parameters and an analysis of the performance gain. Various sets of parameters are studied and optimized with respect to the link performance. Furthermore, an algorithm was provided to compute the optimum values of the MBSE parameters according to some constraints, we have implemented MBSE in two UDcast DVB-SH equipments and we have validated our optimization method using intensive experiments with typical usage scenarios under a hardware-emulated wireless link.
