Abstract:
A wireless OFDM transceiver uses a method of detecting subcarrier characteristics, such as phase and amplitude, to determine the bandwidth of a received packet. By detecting different subcarrier characteristics in the long training symbols of a packet at the receiver, the packet is associated with different bandwidths. The different bandwidths are used in a wireless network where devices can communicate using two frequency bands that overlap one another and where one is wider than the other.
