Method and system for diversity processing utilizing a programmable interface suppression module

A system for digital signal processing, the system comprising:

• one or more circuits comprising a plurality of interference suppression modules, wherein said one or more circuits are configured to:
• adjust said plurality of interference suppression modules based on one or more interference cancellation parameters, wherein each of said plurality of interference suppression modules corresponds to one of a plurality of receiving antennas;
• compute a plurality of weighting factor values at said plurality of interference suppression modules based on said one or more interference cancellation parameters and a plurality of multipath signals received via said plurality of receiving antennas;
• generate, at said plurality of interference suppression modules, a plurality of estimated signals based on said plurality of weighting factor values;
• receive, at said plurality of interference suppression modules, a plurality of residual signals, wherein said plurality of residual signals is generated based on said plurality of estimated signals and said plurality of multipath signals;
• generate, at said plurality of interference suppression modules, a plurality of updated estimated signals based on said plurality of estimated signals;
• receive, at said plurality of interference suppression modules, a plurality of updated residual signals, wherein said plurality of updated residual signals is generated based on said plurality of residual signals and a plurality of incremental signals computed from said plurality of updated estimated signals and a plurality of addback signals;
• and
• generate, at said plurality of interference suppression modules, a plurality of interference suppressed signals based on said plurality of updated residual signals.
