1. A wireless Orthogonal Frequency Division Multiplexing (OFDM) transceiver comprising: a transmitter portion, that cooperates with a controller and memory, capable of generating a packet comprising a preamble portion and a header portion wherein a sub-carrier spacing of a section of the preamble portion is greater than the sub-carrier spacing of the header portion; the transmitter portion further of capable of encoding a plurality of bits using a Forward Error Correction (FEC) encoder to generate a FEC codeword comprising a plurality of encoded bits; and the transmitter portion further capable of concatenating a first copy of the FEC codeword with a second copy of the FEC codeword, wherein the concatenating comprises cyclically shifting by two bits the second concatenated copy of the FEC codeword relative to the first concatenated copy of the FEC codeword.
