A wireless communication unit (100 fig.1) comprises a receiver coupled to a digital signal processor (DSP) 108 comprising logic 205 to perform a fast Fourier transform (FFT) on a received signal from a second wireless communication unit. The FFT logic 205 is coupled to signal determination logic 210 arranged to compare a FFT signal to a number of stored FFT signals and determine whether to further process the received signal to acquire synchronisation with a transmission of the second wireless communication unit. The signal determination logic 210 may analyse the behaviour of the received signal, e.g. the respective amplitude of the received baseband signal in a frequency domain, in order to identify a bit sequence of the received signal. |
