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

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.
