Abstract
A system for automatically detecting the PHY mode based on the incoming preamble is disclosed. The system includes a multimode demodulator, which includes a preamble detector and a demodulator. The preamble detector is used to determine when the preamble has been received and the PHY mode being used by the sending node. An indication of the PHY mode is supplied to the demodulator, which then decides the incoming bit stream in accordance with the detected PHY mode. In some embodiments, one demodulator, capable of decoding the bit stream in accordance with a plurality of PHY modes is employed. In other embodiments, the system includes a plurality of demodulators, where each is dedicated to one PHY mode.
