Abstract: Aspects of the disclosure provide a method for detecting interference. The method includes receiving a plurality of frequency components of a signal received at a first device, identifying, among the plurality of frequency components, first frequency components that are not corrupted by interference, determining a noise power threshold based on the first frequency components, and comparing powers of the plurality of frequency components with the noise power threshold to determine second frequency components to be suppressed during decoding of the signal.

Abstract: A packet is detected in an input data stream. A stream of fast Fourier transform (FFT) blocks are scanned for a plurality of candidate symbols for a preamble of the packet. The stream of FFT blocks correspond to the input data stream. A symbol boundary is detected between adjacent candidate symbols of the plurality of candidate symbols. The FFT blocks are aligned with the symbol boundary. A transition boundary is detected between different adjacent candidate symbols of the preamble based on the detected symbol boundary. A packet detection indication is provided based on the detected transition boundary.
