Abstract
A preamble channel encoder, e.g., in a UHDR-DO system, uses a channel structure that can efficiently transmit more information bits, yet achieve sufficient detection and false alarm performance. The preamble channel encoder uses tail-biting convolutional coding and Cyclical Redundancy Check (CRC). The preamble channel structure can be used to encode, e.g., rate indicator bits, while a MAC identifier encoder, e.g., a Reed-Solomon encoder, is used to encode MAC identifier bits. The encoded rate indictor and MAC identifier bits can then be mapped to the appropriate tones in an OFDM encoding scheme.
