Abstract
A low cost wireless multi-band communications device automatically adapts itself to a signal received from a particular system. On the basis of a bandwidth determination of the received signal, a sampling bandwidth and/or sampling time is selected and/or derived for down mixing the received signals. Improved noise immunity is provided via a band limiting of the sampling means. An adaptive filter is coupled to the output of the sampling means and is adjusted in to obtain a satisfactory level of adjacent channel interference rejection.
