Abstract
A data detector is disclosed. The data detector includes a memory and processing circuitry interfaced with the memory. The processing circuitry is configured to receive a digital signal representative of a radio frequency signal in the digital domain. The processing circuitry generates a frequency offset estimate derived from the digital signal and outputs the frequency offset to the memory and in turn receives output from the memory a set of coefficients that corresponds to the frequency offset estimate. The processing circuitry then performs a complex correlation between the digital signal and the set of coefficients to determine a maximum peak correlation.
