1. A method for compressive sensing tap identification for channel estimation comprising:

  • identifying a set of significant taps in the time domain;

    representing a time-flat channel response using a Taylor series expansion with the set of significant taps;

    converting the time-flat channel response to a vectorized channel response;

    transforming the vectorized channel response to a compressive sensing (CS) polynomial frequency response;

    aggregating the CS polynomial frequency response into a stacked frequency response;

    converting the stacked frequency response into a measured pilot frequency response;

    estimating a channel parameter vector based on the measured pilot frequency response; and

    generating a reconstructed channel response from the channel parameter vector.
