Iterative interference cancellation receiver

A receiver comprising:

• an antenna configured to receive a burst of symbols;
• a timing estimator configured to generate a plurality of timing hypotheses for the burst of symbols;
• a processor configured to calculate a corresponding plurality of weights for each of the plurality of timing hypotheses based on a subset of the burst of symbols;
• an interference suppression filter configured to:
• filter the subset of the burst of symbols with the corresponding plurality of weights for each of the plurality of timing hypotheses;
• and
• filter the burst of symbols with a first plurality of weights corresponding to a selected timing hypothesis, wherein the processor is configured to select the selected timing hypothesis based on a midamble estimation error of the selected timing hypothesis;
• a decoder configured to decode the filtered burst of symbols to generate data corresponding to the burst of symbols;
• an encoder configured to encode the data to generate a re-encoded burst of symbols;
• the processor configured to calculate a second plurality of weights for the interference suppression filter based upon the re-encoded burst of symbols;
• the interference suppression filter configured to filter the re-encoded burst of symbols with the second plurality of weights;
• and
• the decoder configured to decode the filtered re-encoded burst of symbols.
