Transmitting a frame may include determining a numerology according to a channel bandwidth, indicating the numerology in a field of a frame, and transmitting the frame using the numerology. Receiving a frame may include receiving a preamble of a frame, determining a numerology using the preamble, and receiving later portions of the frame using the numerology. Transmitting a frame may include, for a transmission time slot, determining a value of a first subcarrier of a first Space-Time Stream (STS), determining a value of a second subcarrier of the first STS, and determining, according to complex conjugates or negative complex conjugates of the values of the first and second subcarriers of the first STS, respective values of second and first sub carriers of a second STS. Transmitting a constellation point of a frame may be performed using an orphan subcarrier pair.
