Use of DVB-T and DVB-S2 in telecardiology

Simulation of Dvb-s2 Transmission in Matlab

This contribution is focused on simulation of the DVB-S2 (Digital Video Broadcasting – Satellite 2nd generation) digital television transmission. For this simulation an application in MATLAB has been developed. It can be use for simulation of whole processing in DVB-S2 transmitter including stream adaptation, FEC (Forward Error Correction) coding with interleaving, modulation, channel distortio...

About QoS in DVB-S2/RCS Systems

The standardization of a Return Channel via Satellite and the satellite community efforts in term of interoperability over the last few years stands for major milestones in the development of reliable, efficient and low cost satellite equipments. It leads to quite a positive outcome: geostationary satellite networks are expected to play a decisive role in bridging the existing digital divide th...

Implementation Challenges and Synergistic Benefits of Dvb-s2 and Dvb-rcs

Advantech believes that the combined use of DVB-S2 and DVB-RCS technologies, plus complementary technologies such as Ka band satellites, can produce a very low cost broadband delivery platform for both broadcast and interactive services. A return channel is rapidly becoming mandatory to serve both the needs of the content provider and to enable delivery optimisations (such as adaptive coding an...

Symbol Rate Estimation for DVB-S2 Broadcasting

Investigation on DVB-S2 Channel Characteristics

This article represents the results of a simulation study of the characteristics of a satellite television channel shaped under the DVB-S2 standard. The formulas for determining BER of a radio channel when using QPSK, 8QPSK and 16APSK modulation are produced. The algorithms determining the probability of error after LDPC and BCH decoders are represented. Based on the analysis of the characteris...
