Patent ID: 8358668

Claim:
A processor-implemented method of processing a received signal including a payload portion and a preamble portion, the preamble portion of the received signal being a single carrier signal, the payload portion of the received signal being a single carrier signal or a multiple carrier signal, the method comprising: receiving the preamble portion of the received signal, wherein the preamble portion of the received signal includes a channel estimation sequence; detecting from the channel estimation sequence in the preamble portion of the received signal whether the payload portion of the received signal is a single carrier signal or a multiple carrier signal, wherein (i) a first spreading sequence included in the channel estimation sequence indicates that the payload portion of the received signal is a single carrier signal, and (ii) a second spreading sequence included in the channel estimation sequence indicates that the payload portion of the received signal is a multiple carrier signal; in response to the payload portion of the received signal being a single carrier signal, demodulating the payload portion of the received signal in a single carrier mode; in response to the payload portion of the received signal being a multiple carrier signal, demodulating the payload portion of the received signal in a multiple carrier mode; and storing data from the demodulated payload portion of the received signal in a computer-readable memory.
