Abstract
A method and apparatus are disclosed for searching for a radar signal within signals received by a wireless device. The wireless device may receive signals within a first frequency segment and a second frequency segment, which is adjacent to the first frequency segment. The wireless device may determine Fast Fourier Transform (FFT) bins associated with the first frequency segment and the second frequency segment. The wireless device may combine the FFT bins associated with the first frequency segment and the second frequency segment and may search for the radar signal within the combined FFT bins.
