| 1. A method for estimating a frequency response of a wireless communication channel, the method comprising:
estimating the frequency response of the wireless communication channel based on a subset of a plurality of available tones,
wherein the subset comprises a plurality of equally spaced tones, the equally spaced tones being equally spaced by a spacing
number of the plurality of available tones between the equally spaced tones,
wherein the estimating comprises:
using a received power equal to P*N/S, where P is an average received power for the plurality of available tones, N is a total
available tone number and S is a subset number indicating the subset number of tones in the subset.
