The strategy for the development of television and radio broadcasting in Russian Federation until 2025 specifically states need to ensure reliability uninterrupted broadcasting. quality DVB-T2 is estimated by data transmission rate bit error BER (Bit Error Ratio) stability margin «at last mile» retransmitters’ broadcast zones. distributed client-server system monitoring RF, proposed article, us...

OBJECTIVES The aim of this research work is the development of a low-cost system for telemedicine based on the DVB-T technology. The diffusion of DVB-T standard and the low cost of DVB-T set-top boxes bring the vision of a capillary distribution of tele-home care monitoring systems with easy-to-use patient's interface. METHODS Exploiting the potentiality of the DVB-T set-top box, we transform...

With the prevalence of orthogonal frequency-division multiplexing (OFDM) in many standards, e.g., IEEE 802.11, 802.16, DVB-T, and DVB-T2, a number variant modulation schemes based on OFDM have been proposed, which resort to signal sparsity further enhance spectral efficiency mitigate high peak-to-average ratio (PAPR) problem. Among these variants, with subcarrier (OFDM-SNM) has proven be effici...

In the IST 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...

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...

OBJECTIVES To determine whether samples of dried venous blood (DVB) were an acceptable alternative to serum for detecting measles-specific IgG in a commercial enzyme immunoassay. METHODS Paired samples of serum and DVB were collected from 98 suspected cases of measles and 1153 schoolchildren in Victoria, Australia. All samples were tested using the Dade Behring Enzygnost Anti-Measles-Virus/Ig...

This paper summarizes key technologies and identifies trends in recent terrestrial broadcast standards. For robust service in urban canyons and mobile environments, Orthogonal Frequency Division Multiplexing (OFDM) has proven extremely advantageous and is employed in ISDB-T, DVB-T2, and DTMB standards. Strong Forward Error Correction (FEC) codes are also needed to increase signal robustness. Lo...
