Novel approach for shipborne‐passive bistatic imaging with DVB‐T signals based on MIAA–RID technique
IET Radar, Sonar & Navigation, 2022 The shipborne‐passive bistatic inverse synthetic aperture radar system with digital video broadcasting terrestrial (DVB‐T) signals is very important in the fields of radar imaging, but it suffers from the problems of grating lobes caused by the spectral ...

An FFT Core for DVB‐T/DVB‐H Receivers [PDF]
VLSI Design, 2008 This paper presents the design and implementation of a 2K/4K/8K multiple mode FFT core for DVB‐T/DVB‐H receivers. The proposed core is based on a pipeline radix‐22 SDF architecture. The necessary changes in the radix‐22 SDF architecture to achieve an efficient FFT implementation are detailed.

Measurement of DVB-S and DVB-S2 parameters
2015 23rd International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2015 Satellite television is probably most used satellite technology today. One of the biggest providers is the ASTRA system of geostationary satellites. Television satellite standard widely used is the DVB-S which established a unified standard for a satellite transmission accepted both by customers as well as the industry. Standard DVB-S2 has improvements

Target DoA estimation in passive radar using non-uniform linear arrays and multiple frequency channels [PDF]
, 2018 In this paper we present a robust approach for target direction of arrival (DoA) estimation in passive radar that jointly exploits spatial and frequency diversity. Specifically we refer to a DVB-T based passive radar receiver equipped with a linear array

International Journal of Satellite Communications and Networking, EarlyView., 2023 The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.

DVB-T Positioning with a One Shot Receiver [PDF]
, 2013 In this paper a one shot receiver for DVB-T positioning is presented. DVB-T SFN signals can be used as Signals-of-Opportunity in urban environment to assist GNSS in case the GNSS-only positioning shows degraded performance.
