Patent ID: 8014270

Claim:
A wireless receiver comprising: a multi-carrier correlator that correlates a received signal according to at least one characteristic of a multi-carrier signal and according to a first predetermined communication protocol, the first predetermined communication protocol including orthogonal frequency divisional multiplexing (OFDM); a multi-carrier packet processor that processes the received signal if the multi-carrier correlator indicates a multi-carrier packet, according to the first predetermined communication protocol; a single-carrier correlator that correlates the received signal according to at least one characteristic of a single-carrier signal and according to a second predetermined communication protocol; a single-carrier packet processor that processes the received signal in response to the single-carrier correlator indicating a single-carrier packet, and according to the second predetermined communication protocol; and a correlation monitor, coupled to the single-carrier and multi-carrier correlators, the correlation monitor configured to continuously monitor correlation results until a packet is detected.
