Apparatus and method for decoding signals

摘要

New capabilities will allow conventional broadcast transmission to be available to mobile devices. A method of decoding a bitstream is described including receiving a demodulated bitstream, the demodulated bitstream encoded using a byte-code encoding process, arranging a portion of the demodulated bitstream into a subset of bits, reordering the subset of bits, and decoding the subset of bits based on a property of the subset of bits and the encoding process. An apparatus includes means for decoding a bitstream based on a property of the subset of bits and the encoding process.

1. A method of decoding a bitstream, comprising:
receiving a demodulated bitstream, the demodulated bitstream encoded using a byte-code encoding process; arranging the demodulated bitstream into a plurality of subsets, each subset containing a plurality of bits; identifying a set of symbols in each of the subsets, each symbol including at least two bits in the subset, the set of symbols related to a modulation format for the demodulated bitstream; reordering the set of symbols in each subset of the plurality of subsets; and decoding each reordered subset based on a trellis relationship between the set of symbols in the reordered subset and a parity checking relationship between the bits in the reordered subset.
