摘要:
Methods and architectures for blind detection of physical layer control (PLC) signaling for transmitters and receivers having respective misaligned inverse fast Fourier transforms (IFFTs) and (FFTs) includes opening a frequency tracking offset calibration circuit, estimating or calculating a phase discontinuity due to FFT misalignment, closing the frequency tracking offset calibration circuit and applying a frequency correction that includes a frequency offset less the calculated or estimated phase discontinuity.
