Abstract
Aspects of a method and system for detecting Bluetooth signals utilizing a wideband receiver are provided. In this regard, a frequency band may be scanned by receiving signals on each of a plurality of sub-bands for an amount of time, the energy received in each band may be compared to a threshold, and whether each sub-band comprises a Bluetooth transmission may be determined based on a FFT. Additionally, the FFT may enable determining on which Bluetooth channel a detected transmission occurred. A FFT may be performed when energy detected in a sub-band is higher than a threshold. The sub-bands may each be a WLAN channel. A type of a detected Bluetooth transmission may be determined based on a number of scans in which the transmission is detected. Each sub-band may be received for less than or equal to 68 μs divided by the number of sub-bands.
