Abstract

A method and architecture for processing signal communications between an encoder and decoder operating according to the ATSC standard adapted for mobile handheld transmission is disclosed. Specifically, a method and apparatus of determining a trellis decoder state from a received training signal is disclosed by examining the received bytes and comparing the received transition sequence against stored transition sequences.
