Investigation on DVB-S2 Channel Characteristics
نویسندگان
چکیده
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 characteristics of the DVB-S2 channel, its noise immunity is evaluated, as well as the permissible transmission rate of video information and the power efficiency of the system.

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...
متن کاملOptimal DVB-S2 spectral efficiency with hierarchical modulation
We study the design of a DVB-S2 system in order to maximise spectral efficiency. This task is usually challenging due to channel variability. The solution adopted in modern satellite communications systems such as DVB-SH and DVB-S2 relies mainly on a time sharing strategy. Recently, we proposed to combine time sharing with hierarchical modulation to increase the transmission rate of broadcast s...
متن کاملGeneric Approach for Hierarchical Modulation Performance Analysis: Application to DVB-SH and DVB-S2
Broadcasting systems have to deal with channel variability in order to offer the best rate to the users. Hierarchical modulation is a practical solution to provide different rates to the receivers in function of the channel quality. Unfortunately, the performance evaluation of such modulations requires time consuming simulations. We propose in this paper a novel approach based on the channel ca...
