A wireless communication system is provided that detects a frequency burst (FB) through analysis of the autocorrelation function of received signals. The system can accommodate the relatively large frequency offsets that are associated with less expensive reference frequency crystals. In one embodiment,...http://www.google.com/patents/US7567637?utm_source=gb-gplus-sharePatent US7567637 - Wireless communication system and method with frequency burst acquisition feature using autocorrelation and narrowband interference detection
