New Challenges to Designers of Digital Terrestrial Television Receivers Concerning Interference

This paper examines the interference mechanisms by which signals on first adjacent channels to any DTV channel may cause harmful interference, and how signals on any UHF channel formerly considered to be a UHF taboo channel (and hence left vacant) may cause interference to digital terrestrial television broadcasting (DTTB) reception. Further, the non-linearity of receivers under strong signal conditions from two or more undesired signals on certain pairs of channels can cause interference to reception of signals on two UHF DTV channels.
