Coexistence Without Interference: Interference Mitigation on DVB-T Reception Caused by Neutral Systems Operating in the Digital Dividend Band

Abstract

The migration from analog to digital television (TV) broadcasting has introduced significant improvements in terms of spectral efficiency. As a result, the number of radio channels required to ensure equivalent coverage has been dramatically reduced [1]. This efficiency gain has allowed the release of a valuable portion of spectrum (previously assigned to analog TV broadcasting) in the 790-862-MHz subband (channels 61-69), often called the digital dividend. This 72-MHz slice of the spectrum is now assigned exclusively to international mobile telecommunications (IMT) [2], [3]. Vis á vis the mobile communications markets, the current data dynamics demand more wireless access to cope with the growing user consumption of mobile services.
