A filter and processing sequence is described that efficiently combines
and performs two or more tasks required to demodulate a composite 3G
(third generation) wireless signal formed by a combination of wideband
3.84 MHz (Universal Mobile Telecommunications System, identified, as
acronym "UMTS", or Universal Mobile Telecommunications System Terrestrial
Radio Access, identified as acronym "UTRA") carriers and narrowband
1.2288 MHz CDMA-2000 carriers. The three tasks, applied to each spectral
component of the 3G wireless signal and described in the order of a
traditional filtering structure are: Spectral translation, Bandwidth
Reduction, and Sample Rate Selection. These tasks are traditionally
implemented in three distinct pieces of hardware or software modules.
