1. A method for channel estimation comprising:

  • determining a channel impulse response using a Taylor series expansion with a plurality of Taylor series coefficients;

    determining a channel frequency response based on the channel impulse response;

    collecting the channel frequency response over a plurality of symbols to obtain a composite channel frequency response;

    generating a sensing matrix based on the Taylor series expansion; and

    determining the plurality of Taylor series coefficients based on the composite channel frequency response and the sensing matrix using compressive sensing channel estimation.
