Abstract
A wireless receiver that sorts packets including a packet detector, multiple correlators, and multiple packet processors. Each correlator correlates a received signal according to packet type. Each packet processor processes the received signal according to packet type. A signal power detector may be provided to initially qualify the received signal as containing a packet, and the correlators determine whether a packet is present. The correlators may be configured for sequential or simultaneous correlation. For the simultaneous correlator configuration, a correlation monitor is provided to monitor correlation results to determine if the received signal contains a packet, and if so, to determine packet type. A low SNR packet detector may be provided which correlates the received signal to detect weak packet signals. The signal power detector may be omitted, where the correlators simultaneously monitor the received signal while a correlation monitor continuously monitors correlation results for packet detection.
