Abstract:
1. An apparatus for dynamically adjusting receiver bandwidth for a receiver device receiving received signals in a communication system; the apparatus comprising: (a) a receiver clock unit coupled with said receiver device for driving said receiver device; said receiver clock unit operating according to at least one receiver clock parameter for effecting sampling of said received signals; said at least one receiver clock parameter being affected by at least one feature of said received signals; (b) a local clock unit operating according to a local clock periodicity; (c) a tracking unit coupled with said receiver device and with said local clock unit; said tracking unit receiving from said receiver device at least one indicator related to said at least one receiver clock parameter; said tracking unit generating at least one tracking parameter for quantifying a comparison between said at least one receiver clock parameter and said local clock periodicity; (d) a counter unit coupled with said tracking unit; said counter unit counting events associated with said at least one tracking parameter; said counter unit generating an event count indicating at least one characteristic relating to said received signals; (e) a decision unit coupled with said counter unit; said decision unit reckoning said event count to appraise said at least one characteristic; said decision unit generating at least one decision parameter relating to said reckoning; and (f) an output logic unit coupled at least with said decision unit, said tracking unit and said receiver clock unit; said output logic unit evaluating said at least one decision parameter and said at least one tracking parameter according to a predetermined logical routine for determining whether a need exists for changing said operating of said receiver clock unit; said output logic unit generating at least one change signal to effect at least a portion of said changing when said evaluating indicates said need exists.
