1. A method for wireless communication by a wireless communication device, comprising:
transmitting a physical layer protocol data unit (PPDU) via a wireless channel, the transmission of the PPDU comprising:
transmitting a data field via a first set of subcarriers of the wireless channel;
transmitting, simultaneously with the transmission of the data field, a duplicate of the data field via a second set of subcarriers of the wireless channel, the duplicate of the data field being transmitted with a phase rotation applied to at least one subcarrier of the second set of subcarriers; and
transmitting a long training field (LTF) via a third set of subcarriers of the wireless channel, the third set of subcarriers including the first set of subcarriers and the second set of subcarriers, the LTF carrying an LTF sequence associated with demodulating the data field and the duplicate data field.
