Abstract
Methods and apparatus for enhancing estimations of channel response in a wireless communication system are discussed. As an example, a method can comprise: selecting a selected channel from among one or more channels in the communication system; determining, for the selected channel, an initial channel estimate comprising a sequence of frequency-domain samples; determining a phase slope of the initial channel estimate; generating a flat-phase channel estimate by removing the phase slope from the initial channel estimate; and generating an enhanced channel estimate for the selected channel by applying a smoothing function to the flat-phase channel estimate. Other aspects, embodiments, and features are also claimed and described.
