Abstract
In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, information bits to be included in the PHY data unit are encoded using a forward error correction (FEC) encoder. Also, the information bits are encoded according to a block coding scheme, where m copies of each bit are included in the information bits, and one or more bits in the m copies of each bit are flipped. The information bits are mapped to a plurality of constellation symbols, and a plurality of orthogonal frequency division multiplexing (OFDM) symbols are generated to include the plurality of constellation symbols. The PHY data unit is generated to include the plurality of OFDM symbols.
