Abstract:
1. A receiving device, comprising: a first signal processor, for receiving a radio frequency signal, and converting the radio frequency signal to generate a first signal, wherein the radio frequency signal comprises a plurality of frames; a second signal processor, coupled to the first signal processor, for performing a Fourier transform operation on the first signal according to a synchronization signal to generate an output signal; a first filter, coupled to the first signal processor, for filtering the first signal to generate a second signal; and a synchronization detection circuit, coupled to the first filter, for detecting the second signal to generate the synchronization signal; wherein the first signal comprises a channel signal and at least a portion of neighboring channel signals from neighboring channels, the second signal comprises a null period of the channel signal, and the output signal corresponds to the channel signal, and the first signal processor comprises:
