  • Receive signal detection of multi-carrier signals
    Patent number: 8693561
    Abstract: Apparatuses, methods and systems of receive signal detection of a multi-carrier signal are disclosed. One method includes receiving a multi-carrier signal, determining a characteristic of each sub-carrier of the multi-carrier signal, and selecting a one of a plurality of receive signal detection techniques for each sub-carrier of the multi-carrier signal based on the determined characteristic of the sub-carrier.
    Type: Grant

  • Link quality prediction
    Publication number: 20070211641
    Abstract: A method and apparatus of predicting link quality of a link is disclosed. The method includes receiving multi-carrier modulated signals over a period of time, estimating an SNR for each received sub-carrier, constructing a sequence of the SNRs, and estimating link PER based upon knowledge of encoding and/or interleaving used during transmission, and the sequence of SNRs.
