摘要： Systems and methods are provided for processing a payload portion of a received signal in a single carrier mode or a multiple carrier mode based on a portion of the received signal. A single carrier signaling portion is received at a first rate, and whether the payload portion of the signal is a single carrier signal or a multiple carrier signal is detected from the received single carrier signaling portion. The payload portion of the received signal is received at the first rate and demodulated in a single carrier mode if the detecting determines that the payload portion of the received signal is a single carrier signal, and the payload portion of the received signal is demodulated in a multiple carrier mode if the detecting determines that the payload portion of the received signal is a multiple carrier signal.

At least one of i) a sequence in the first field serves as a cyclic prefix of the first CES symbol, ii) a beginning portion of the second CES symbol serves as a cyclic postfix of the first CES symbol, or iii) an ending portion of the first CES symbol serves as a cyclic prefix of the second CES symbol.
