Cloud Transmission: System Performance and Application Scenarios
(IEEE, 2014)
[EN] Cloud Transmission (Cloud Txn) System is a
flexible multi-layer system that uses spectrum overlay technology
to simultaneously deliver multiple program streams with
different characteristics and robustness for ...
Performance Study of Layered Division Multiplexing Based on SDR Platform
(IEEE, 2015-06-05)
[EN] Two of the main drawbacks of the current broadcasting services are, on the one hand, the lack of flexibility to adapt to the new generation systems requirements, and on the other hand, the incapability of taking a ...
A Measurement-based Multipath Channel Model for Signal Propagation in Presence of Wind Farms in the UHF Band
(IEEE, 2013-10-15)
[EN] Scattering signals on wind turbines may lead to
degradation problems on the communication systems provided
in the UHF band, such as terrestrial television broadcasting,
broadband wireless systems or public safety ...
A comparative study of the field strength prediction methods in the MW band
(IET, 2008-10-23)
[EN] The recently developed digital radio systems for the MW band require accurate field
strength prediction algorithms for coverage estimation. This paper presents a
comparison of the estimation accuracy provided by the ...
Empirical Evaluation of the Impact of Wind Turbines on DVB-T Reception Quality
(IEEE, 2011-12-09)
[EN] This paper describes the results of two extensive measurement campaigns for evaluating the potential impact of scattered signals from wind turbines on terrestrial DTV reception quality in the UHF band. A detailed ...
An Empirical Comparative Study of Prediction Methods for Estimating Multipath Due to Signal Scattering from Wind Turbines on Digital TV Services
(IEEE, 2011-04-29)
[EN] Several authors have theoretically studied the
effect of wind turbines on the propagation of electromagnetic
waves in the UHF band. The International Telecommunication
Union also proposes a simplified model to ...
Planning Large Single Frequency Networks for DVB-T2
(IEEE, 2015-09)
[EN] The final coverage and associated performance of an SFN is a joint result of the properties of all transmitters in the SFN. Due to the large number of parameters involved in the process, finding the right configuration ...
Impact analysis of wind farms on telecommunication services
(Elsevier, 2014-01-25)
[EN] Wind power is one of the fastest-growing technologies for renewable energy generation. Unfortunately, in the recent years some cases of degradation on certain telecommunication systems have arisen due to the presence ...
Large size FFTs over time-varying channels
(IET, 2014-06-01)
[EN] In orthogonal frequency division multiplexing (OFDM) signals, the usage of large size fast Fourier transforms (FFTs) reduces the guard interval percentage, and therefore increases the data throughput reducing the data ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
