Abstract
A method for encoding a bitstream for a frame in a wireless transmission is described. The method includes receiving, by an error correction unit of the wireless device, the bitstream; performing, by the error correction unit, forward error correction on the bitstream to generate an error corrected bitstream; determining, by a dual sub-carrier modulation (DCM) mapper of the first wireless device, a number of data subcarriers for modulating the error corrected bitstream to subcarriers in each half of an orthogonal frequency-division multiplexing (OFDM) symbol, wherein the number of data subcarriers is determined to be (1) 26 for a first bandwidth of the frame, (2) 54 for a second bandwidth and performing, by the DCM mapper, DCM on the error corrected bitstream based on the determined number of data subcarriers to generate a stream of complex numbers corresponding to the number of data subcarriers.
