In a method for generating a PHY data unit for transmission via a communication channel, a modulation scheme is selected from a plurality of modulation schemes, information bits are encoded to generate encoded data using one or more encoders, and an interleaving parameter NCOL is selected using the selected modulation scheme. NCOL varies for different modulation schemes. The encoded data is interleaved, which includes entering the encoded data into NROW rows and reading the encoded data out in NCOL columns. The payload information of the PHY data unit is modulated according to the modulation scheme, and a plurality of OFDM symbols is formed based on the modulated payload information. |

1. A method, implemented in a communication device, for generating a physical layer (PHY) data unit for transmission via a communication channel, the method comprising:
selecting, in the communication device, a modulation scheme from a plurality of modulation schemes; encoding, in the communication device, information bits to generate encoded data using one or more encoders; selecting, in the communication device, an interleaving parameter NCOL using the selected modulation scheme, wherein NCOL varies for different modulation schemes; interleaving, in the communication device, the encoded data, including entering the encoded data into NROW rows and reading the encoded data out in NCOL columns; modulating, in the communication device, the payload information of the PHY data unit according to the modulation scheme; and forming, in the communication device, a plurality of OFDM symbols based on the modulated payload information. |
