1. A processing engine, comprising:
- one or more matrix generators, wherein each of the one or more matrix generators is configured for generating a matrix comprising elements of an interfering signal selected for suppression;
a processor communicatively coupled to the one or more matrix generators and configured for generating one or more suppression operators; and
one or more applicators, wherein each applicator is communicatively coupled to the processor and configured for applying at least one of the one or more suppression operators to an input signal to substantially suppress at least one of the interfering signals.

Abstract
A multi-mode receiver includes a channel decomposition module (e.g., a Rake receiver) for separating a received signal into multipath components, an interference selector for selecting interfering paths and subchannels, a synthesizer for synthesizing interference signals from selected sub channel symbol estimates, and an interference canceller for cancelling selected interference in the received signal. At least one of the channel decomposition module, the synthesizer, and the interference canceller are configurable for processing multi-mode signals.
