Abstract
A method of interleaver design for dual carrier modulation (DCM) is proposed in a wireless network. For HE PPDU transmission with DCM, information bits are first encoded by a BCC encoder. The BCC encoded bit streams are then interleaved by a BCC interleaver. More specifically, the BCC interleaved bits are repeated on two halves of a given resource unit (RU). The BCC interleaver parameters are defined based on half of the total number of the data tones of the RU if DCM is applied. The BCC interleaved bits are then modulated and mapped to two halves of the RU by a DCM constellation mapper.
