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, the system includes FB search hardware that operates in two modes, namely an FB location mode with narrowband interference (e.g. CW or continuous wave) detection and an FB location mode without such narrowband interference detection, depending on whether a CW signal (carrier or other narrowband interferer) is present or not.
