Patent ID: 8238479

Claim:
A receiver configured to synchronize to a received signal, comprising: an analog to digital converter, configured to convert the received signal to a digital signal; a baseband processor, configured to convert the digital signal to a baseband signal; a Fast Fourier Transform processor, configured to convert the baseband signal to a frequency domain signal; and a pilot processor, configured to determine a coarse frequency offset (CFO) and timing and carrier information from the frequency domain signal, wherein the baseband processor is further configured to receive the CFO and apply the CFO in converting the digital signal to the baseband signal; a wideband low-pass filter, configured to receive and filter the baseband signal; a narrowband low-pass filter, configured to receive and filter the baseband signal; and a selector in communication with the wideband low-pass filter and the narrowband low-pass filter, the selector configured to receive the CFO from the pilot processor, wherein upon receipt of the CFO, the selector is configured to select the narrowband low-pass filter.
