Enhancing mobile services with DVB-S2X superframing

DVB-S2x Enabled Precoding for High Throughput Satellite Systems

Multi-user Multiple-Input Multiple-Output (MU-MIMO) has allowed recent releases of terrestrial LTE standards to achieve significant improvements in terms of offered system capacity. The publications of the DVB-S2x standard and particularly of its novel superframe structure is a key enabler for applying similar interference management techniques -such as precodingto multibeam High Throughput Sat...

Antenna diversity for DVB-S2 mobile services in railway environments

This paper evaluates the applicability of the DVB-S2 standard in railway environments, where the most peculiar impairment is the periodic deep fading caused by power-supply arches distributed along the rail tracks. This effect induces a link loss every time the train antenna undergoes a power arch and cannot be counteracted with transmission power. Therefore, we propose and investigate the use ...

Cross-Layer Optimization of DVB-T2 System for Mobile Services

Mobile broadcast services have experienced a strong boost in recent years through the standardization of several mobile broadcast systems such as DVB-H, ATSC-M/H, DMB-T/H, and CMMB. However, steady need for higher quality services is projected to surpass the capabilities of the existing mobile broadcast systems. Consequently, work on new generations of mobile broadcast technology is starting un...

Hybrid Mobile Interactive Services combining DVB-T and GPRS

Scarce wireless bandwidth and limited capabilities of cellular systems demand new, complementary techniques for the provision of wireless multimedia services. Hybrid systems coupling for example the digital terrestrial television (DVB-T) system with cellular communication systems provide a feasible solution to this problem. This paper describes a hybrid system, composed of DVB-T and the new GSM...
