Coded Orthogonal Frequency Division Multiplexing Method and Apparatus

摘要

A method and apparatus for transmitting and receiving data via guard tones are described. The information bits are coded by convolutional encoder ( 101 ) and some of the punctured bits from punctured ( 102 ) are selected with bit selector ( 105 ) and subject as the punctured data to interleaving by an interleaver ( 106 - 103 for the punctured data-). The OFDM process that follows ( 104, 107, 108 ) maps the interleaved selected punctured bits to guard tones and the interleved punctured data to data sub-carriers.
