  • METHOD AND SYSTEM FOR ADAPTIVE DUPLICATED FILTERS AND INTERFERENCE CANCELLATION
    Publication number: 20090296786
    Abstract: A method and device substantially cancel at least Multiple Access Interference (MAI) and Inter-Symbol Interference (ISI) while detecting a received spread spectrum signal in a multi-user communication system. For that purpose, a plurality of stages are formed, each comprising processing the received spread spectrum signal through an interference cancelling function to produce an essentially MAI- and ISI-free signal, and processing the essentially MAI- and ISI-free signal through a reconstruct received spread spectrum signal function to produce a received spread spectrum signal essentially free from MAI and ISI. The plurality of stages are cascaded to successively process the spread spectrum signal and improve cancellation of MAI and ISI from the spread spectrum signal.
