Patent ID: 7822139

Claim:
A method for communicating a training sequence for initializing an equalizer in a digital receiver, comprising the steps of: receiving a digital signal containing data to be broadcast from a digital RF transmitter; inserting training sequence data into the digital signal at predetermined byte locations based on a mapping of an ATSC (Advanced Television Systems Committee) A/53 data interleaver such that a continuous predetermined sequence of symbols is generated from the training sequence data and communicated to the digital receiver at known locations within a broadcast ATSC A/53 VSB (vestigial sideband) data frame; and inserting a plurality of stuff bytes into the digital signal for deterministically initializing a plurality of ATSC A/53 Trellis coders in an exciter of the digital RF transmitter to a known state, wherein the plurality of stuff bytes are inserted prior to encoding the training sequence data into the continuous predetermined sequence of symbols by the plurality of ATSC A/53 Trellis coders, and wherein a first set of bits of each one of the plurality of stuff bytes are used to deterministically reset a respective first set of the plurality of ATSC A/53 Trellis coders, and a second set of bits of each one of the plurality of stuff bytes include a portion of the training sequence data.
