Abstract

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 N COL is selected using the selected modulation scheme. N COL varies for different modulation schemes. The encoded data is interleaved, which includes entering the encoded data into N ROW rows and reading the encoded data out in N COL 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.

First claim

What is claimed is:

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, a number of spatial streams N SS ;
parsin…
