Abstract

Improved DTTV reception in a crowded spectrum can be attained by automatically shifting the front-end filter and by automatically steering the pattern of the receive antenna. This paper shows how 3rd order intermodulation distortion (IM₃) and other interference due to strong adjacent channels can be minimized and the signal to noise ratio maximized for optimally robust reception.
