Patent ID: 7921351

Claim:
A receiver for receiving a data stream of data symbols that have been encoded with a linear block code, said receiver comprising: a complex demodulator that demodulates said data symbols to produce an in-phase component and a quadrature phase component; low pass filters that are connected to said demodulator that low pass filter said in-phase component and said quadrature phase component to remove out-of-band energy; a comparator that compares said in-phase components and said quadrature phase components with predetermined thresholds that indicate in-band impairment of said data symbols and generate control signals that identify data symbols for erasure selected from the group consisting of data symbols that have: in-phase components that exceed said predetermined thresholds, and quadrature phase components that exceed said predetermined thresholds; a wideband overload detector that detects if wideband energy of said data symbols exceeds a wideband energy limit and generates an additional control signal that identifies impaired data symbols that have wideband energy that exceeds said wideband energy limit; a decoder that erases said data symbols that have been identified by said control signals and said additional control signals prior to decoding by said decoder so that the data correction capabilities of said decoder using Reed-Solomon error correction is increased up to t=(n−k), where t=number of corrections, k=number of data bits in a block of data and n=number of data bits plus redundancy bits in a block of data.
