Abstract: A wireless transmission having a header and a payload is sent by transmitting a preamble of the header with a first modulation, wherein the preamble carries a coded modulation indicator. The payload and a remainder of the header are transmitted with a modulation associated with the coded modulation indicator. When the transmission is received, the preamble is demodulated in accordance with the first modulation. The coded modulation indicator is then decoded, and the payload and the remainder of the header are demodulated in accordance with the modulation indicated by the decoded modulation indicator.
