Classification: H04L

Abstract:
A demodulation system comprising:a plurality of detectors, each configured to estimate source bits from a common signal; one or more signal quality estimators for receiving signals embodying the estimated bits from the detectors, and determining one or more performance metrics for the detectors; a selector for receiving the one or more performance metrics from the one or more signal quality estimators, and, responsive thereto, selecting or continuing the pre-selection of one of the detectors; and a multiplexor configured to receive signals embodying estimated bits from the detectors, and, responsive to the selection or pre-selection made by the selector, outputting the estimated bits from one of the detectors, wherein the detectors are configured to provide soft estimates of the source bits, and the system further comprises a decision module configured to provide hard estimates of the source bits from the output of the multiplexor.
