摘要：
A system and method for modulating and coding a signal is disclosed. Data from a Media Access Control (MAC) layer is convolutionally encoded. Robust coding of the data from the MAC layer is performed either before or after the convolutional encoding. The coded data is differentially modulating and then Orthogonal Frequency Division Multiplexed to create an OFDM output signal adapted to be transmitted on a power line network. The robust coding may be a repetition 2 coding or a repetition N coding. The robust coding may add an outer code prior to the convolutional encoding. The robust coding may be Reed Solomon coding performed prior to the convolutional encoding. An optional header for identifying the robust coding is also disclosed along with a method for decoding the header.
