Claim Text:
1. A method for generating an orthogonal frequency division multiplexing (OFDM) symbol to be included in a physical layer (PHY) data unit for transmission via a communication channel, wherein the OFDM symbol includes a plurality of OFDM tones, the method comprising: encoding, using a low density parity check (LDPC) encoder, information bits to be included in the OFDM symbol to generate encoded information bits, wherein two or more code words are used to encode information bits to be included in the OFDM symbol, and wherein encoded information bits corresponding to at least one of the two or more code words are to be entirely included in the OFDM symbol; parsing the encoded information bits into a plurality of spatial streams; for each spatial stream, parsing the encoded information bits into a first frequency portion corresponding to a first subband of the communication channel and a second frequency portion corresponding to a second subband of the communication channel; and for each frequency portion generating the OFDM symbol to be included in the PHY data unit.
