Digital television terrestrial broadcasting (DTTB) networks can help to alleviate the congestion problem in cellular networks by delivering rich contents to a large number of clients simultaneously. In particular, recently, there is a strong interest of extending current DTTB systems to support multimedia broadcasting services. The lack of return channel and long transmission time interval howe...

Digital multimedia broadcasting is available in more and more countries with various forms. One of the most successful forms is Digital Video Broadcasting for Terrestrial (DVB-T), which has been deployed in most countries of the world for years. In order to bring the digital multimedia broadcasting services to battery-powered handheld receivers in a mobile environment, Digital Video Broadcastin...

Context: The thesis work will be carried out in the Algorithm-Silicon Interaction team of the “Laboratoire des Sciences et Techniques de l’Information, de la Communication et de la Connaissance” (Lab-STICC), research unit UMR 6285 of the French National Scientific Research Centre. The research activity of the team is mainly dedicated to the development of new algorithms and architectures for di...

In this study, we propose the spectrum sensing technology of DVB-T2 and Wi-Fi 6 for cognitive radio systems. The implemented detectors use unique preamble characteristics signals. performance is optimized in a channel where signals are mixed along with signal-to-noise ratio (SNR) over range −10 dB to 10 dB. detector uses an autocorrelation that applies distinctive each signal preamble. Threshol...
