Abstract
In one aspect, an apparatus includes: a fast Fourier transform (FFT) engine to receive orthogonal frequency division multiplexing (OFDM) samples of one or more OFDM symbols and convert the one or more OFDM samples into a plurality of frequency domain carriers; and a tone cancellation circuit coupled to the FFT engine to receive the one or more OFDM samples and generate a plurality of frequency carriers for the one or more OFDM samples, identify a highest magnitude frequency carrier of the plurality of frequency carriers, and remove tone interference from the OFDM samples based at least in part on the highest magnitude frequency carrier.
