Patent ID: 8879658

Claim:
An interference suppressor for suppressing at least one of inter-cell and intra-cell interference in multiple-access communication signals received by a plurality of antennas, comprising: a front-end processing module configured for receiving constituent signals of the received multiple-access communications signals and generating input symbol decisions; and one or more interference suppression units configured for processing the input symbol decisions into updated symbol decisions, each of the one or more interference suppression units comprising: a despreader configured to resolve each of a plurality of error signals corresponding to each of a plurality of antennas onto a signal basis for the one or more transmission sources for producing a plurality of resolved error signals; a first combiner configured for combining the resolved error signals across antennas for producing a combined signal; a stabilizing step-size module configured to scale the combined signal by a stabilizing step size for producing a scaled signal; and a second combiner configured for combining the combined signal with a weighted input vector.
