Selectable interference cancellation in a communications receiver

摘要

Method and apparatuses are disclosed to substantially compensate for various unwanted interferences and/or distortions within a communications receiver. Each of these apparatuses and methods estimate the various unwanted interferences and/or distortions within the communications receiver. Each of these apparatuses and methods remove the estimates of the various unwanted interferences and/or distortions within the communications receiver from one or more communications signals within the communications receiver to substantially compensate for the various unwanted interferences and/or distortions.

主权项

1. An apparatus for cancelling unwanted interference imposed on a received communications signal, comprising:
a plurality of front end modules configured to process the received communications signal to provide a digital sequence of data, each of the plurality of front end modules being configured to compensate for a different unwanted interference from among a plurality of unwanted interferences; a spectrum estimation module configured to classify unwanted interference remaining within the digital sequence of data to provide a spectrum estimate; and a front end allocation module configured to select an optimal front end module from among the plurality of front end modules that is optimized to compensate for the unwanted interference remaining within the digital sequence based upon the spectrum estimate.
