TV white space (TVWS) refers to the unused UHF and VHF spectrum owned by primary users, such as (DVB-T2) broadcasters in a certain location. The protection of users' interference from devices has been major implementation issue. Protection ratio setting is commonly used limit amount transmission power that can permit. In present study, simulation experiment for proposed values are compared. Sim...

In the DRiVE project, a flexible, hybrid communication system has been developed which performs dynamic allocation of spectral resources from a common region of spectrum to the participating radio systems. Thus, new spectral neighborhoods emerge, which pose requirements regarding the protection of one system from the adjacent channel interference generated by the other system. As an example, DR...

This paper focuses on detecting anomalies in a digital video broadcasting (DVB) system from providers’ perspective. We learn a probabilistic deterministic real timed automaton profiling benign behavior of encryption control in the DVB control access system. This profile is used as a one-class classifier. Anomalous items in a testing sequence are detected when the sequence is not accepted by the...

This paper aims, a 3D-Pilot Aided Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) Channel Estimation (CE) for Digital Video Broadcasting -T2 (DVB-T2) for the 5 different proposed block and comb pilot patterns model and performed on different antenna configuration. The effects of multi-transceiver antenna on channel estimation are addressed with different pilot po...

This paper analyses the possibility of receiving high data rate multimedia services in the non-stationary urban mobile scenario using the digital video broadcast standard DVBT2. The work focuses on the complex urban mobile environment and presents a comparison between the different configuration parameters and the data rates associated to different video services. The study is based on the expe...

A low-cost passive bistatic radar system using digital video broadcasting satellites (DVB-S) as illuminators of opportunity is presented. The system was developed using off-the-shelf components which a global cost of approximately 100 Euros. To increase the target detectability using DVB-S signals in a non-coherent environment a novel methodology, using a reference target and some basic signal ...

In Europe, the end of the 20 century was the period of the changing to digital systems, including television broadcasting. In Hungary the first digital terrestrial pilot transmissions were started in 1999 and the supplier company plans a start of the full services in autumn 2004, so the time is right to give a brief technical description what is it about and why is it good for us.
