Abstract

Channelized receivers have many uses. They are used for determining the particular frequency band(s) in which signals are active or for separating the interference from various multiple signal emit~ ters closely spaced in frequency. Channelized search detection surveillance receivers and cellular base station receivers are two examples. The channeliza~ tion is typically performed in a filter bank located at a convenient center frequency for the filtering technology used. The center frequency input to this filter bank may not coincide to the absolute center frequency of the signals of interest and must be radio frequency, RF, translated for proper alignment.
