Abstract
METHODS AND SYSTEMS FOR COMMUNICATING IN A WIRELESS NETWORK MAY DISTINGUISH DIFFERENT TYPES OF PACKET STRUCTURES BY MODIFYING THE PHASE OF A MODULATION CONSTELLATION, SUCH AS A BINARY PHASE SHIFT KEYING (BPSK) CONSTELLATION (210), IN A SIGNAL FIELD (114). RECEIVING DEVICES MAY IDENTIFY THE TYPE OF PACKET STRUCTURE ASSOCIATED WITH A TRANSMISSION OR WHETHER THE SIGNAL FIELD IS PRESENT BY THE PHASE OF THE MODULATION CONSTELLATION (210) USED FOR MAPPING FOR THE SIGNAL FIELD (114). IN ONE EMBODIMENT, THE PHASE OF THE MODULATION CONSTELLATION MAY BE DETERMINED BY EXAMINING THE ENERGY OF THE I AND Q COMPONENTS AFTER FAST FOURIER TRANSFORM. VARIOUS SPECIFIC EMBODIMENTS AND VARIATIONS ARE ALSO DISCLOSED. FIGURE 4
