Utilization of Matlab for the Digital Modulation Methods Simulation in Dvb Area
The contribution deals with the utilization of Matlab for simulation and analysis of digital QPSK and M-QAM modulators and demodulators used in DVB (Digital Video Broadcasting) standard. Presented modulators and demodulators are optional modules of simulation system that can evaluate the influence of transmission errors on transmitted digital signal and according visual information. The system ...
متن کاملThe EMBRACE System Demonstrator
Within the EMBRACE project an advanced communications system and network was developed. It uses the DVB technology for the high-speed downlink and a novel multi-frequency TDMA system for the return link. The return link is scaleable to accommodate the variety of data rates. Emphasis was put on providing quality of service (QoS) in wireless IP networks. Site diversity is used to increase the ava...

متن کاملDVB-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...
متن کاملModelling impulsive interference in DVB-T: statistical analysis, test waveforms and receiver performance
Impulsive Interference (II) has been an elusive phenomenon which cast a shadow on the initial launch of Digital Terrestrial Television (DTT) in the UK in 1998. The lack of a suitable time-interleaving scheme in the DVB-T specification makes the system rather sensitive to sources of interference of an impulsive nature. Strategies for improving the performance of DTT in the presence of impulsive ...
