The analyze of MER variation concerning the quality of transmission for DVB-T signals
نویسندگان
چکیده
The analyze of MER (the modulation error) for the DVB-T (Digital Video Broadcasting Terrestrial) signal is studied in this article. The analyze of MER variation was made on the Romanian territory in two locations with and without obstacles. The results show that the DVB-T signal had a better quality and the DVB-T transmissions in the both locations are less affected by the noise. Key-Words: MER, CBER, COFDM, DVB-T, QAM.

Proposed Pilot Pattern Methods for Improvement DVB-T System Performance
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
متن کاملThe analysis of OFDM constellations for Digital Terrestrial Television
The analysis of the OFDM (Orthogonal Frequency Division Multiplexing) constellation for the DVB-T (Digital Video Broadcasting Terrestrial) signal are studied in this article. The measurements were made on the Romanian territory in two locations with and without obstacles. The measured quality parameters of the DVB-T signal are: CBER (BER before Viterbi), the signal power and MER (the modulation...
متن کاملTransmission of Cholera Disease with Laplacian and Triangular Parameters
A mathematical model has been introduced for the transmission dynamics of cholera disease by GQ Sun et al. recently. In this study, we add Laplacian and Triangular random effects to this model and analyze the variation of results for both cases. The expectations and coefficients of variation are compared for the random models and the results are used to comment on the differences and similarit...
متن کاملDVB-T/H Portable and Mobile TV Performance in the New Channel Profiles Modes
This paper deals with an experimental laboratory assessment of new channel profile modes in the transmission of DVB-T/H portable and mobile TV over fading channels. These new profiles called PI (Pedestrian Indoor), PO (Pedestrian Outdoor), VU (Vehicular Urban) and MR (Motorway Rural) are originally from the Celtic Wing TV project. The DVB-T/H performance was tested in a laboratory environment u...
متن کاملDigital Video Broadcast-Terrestrial (DVB-T) Single Frequency Networks Positioning in Dynamic Scenarios
Since Global Navigation Satellite Systems (GNSS) show degraded performance in dense urban and indoor areas, a positioning sensor based on Digital Video Broadcast-Terrestrial (DVB-T) systems is presented in this paper. DVB-T signals can be considered as signals-of-opportunity for positioning, due to their good properties. One of the challenges to overcome is to distinguish the signals from diffe...
