Abstract
A channelizer ( ) for a multi-carrier receiver including a plurality of digital sub-band tuners (DSBTs) ( ). Each DSBT ( ) digitally filters individual carrier data bits from a digital multi-carrier data stream based on a programmable center frequency. Each DSBT ( ) further digitally filters the individual carrier data stream based on a programmable bandwidth. The DSBTs ( ) can be allocated based on modulation format, center frequency, or both. The channelizer ( ) is therefore able to process narrowband carrier data streams as well as wideband carrier data streams. One embodiment of the channelizer ( ) has a plurality of sub-channelizers ( ) and a switch matrix ( ). The sub-channelizers ( ) filter individual carrier data streams from a multi-carrier data stream. The switch matrix ( ) is coupled to the sub-channelizers ( ) and routes the individual data streams to the sub-channelizers ( ) in a desired configuration.
