Patent ID: 8107551

Claim:
A system for recovering data from at least one signal, the system comprising: an analog-to-digital converter (ADC) and in-phase/quadrature (IQ) generator component, comprising a processor, configured to sample a signal recovered from a communication medium on which the signal is propagating to generate a first signal sample and a second signal sample; a Fast Fourier Transform (FFT) component coupled to the ADC and IQ generator component, the FFT component being configured to process the first signal sample to generate a first signal phase and process the second signal sample to generate a second signal phase, wherein the FFT component comprises a first channel and a second channel, the first channel being configured to process the first signal sample and the second signal sample, the second channel being configured to process at least two samples from a second signal to generate at least two phases for the second signal, wherein processing the at least two samples from the second signal at least partially overlaps processing the first signal sample or processing the second signal sample; and a phase difference calculation component coupled to the FFT component, the phase difference calculation component being configured to: determine a phase difference between the first signal phase and the second signal phase; determine a bit value represented by the signal based on the phase difference; and output the bit value to an end device coupled to the phase difference calculation component.
