Joint packet detection in a wireless communication system with one or more receiver

摘要

A packet detector joint detects 802.11 a packets, 802.11 b packets and interference that is within a monitored frequency range but is not formatted as 802.11 a packets or 802.11 b packets. The packet detector can use signals from one or more antennas. Detection of signals is done using differentially detected correlations. In addition to packet detection, the packet detector can identify signal levels, noise levels and locations of narrowband interference. The process of packet detection and identifying other indicators can be done simultaneously and as the signal is being received.
