Wavelet transform-based tracking for estimating an aging wireless channel

Abstract:

Aspects of the disclosure relate to channel estimation and tracking in a wireless communication system. A wireless communication entity estimates a received signal utilizing any suitable process. The wireless communication entity applies a Wavelet decomposition filter to the estimated received signal to generate a channel coefficient estimate. The Wavelet decomposition filter may be configured to employ a Haar mother Wavelet. The wireless communication entity generates a prediction of a future channel estimate at a later time, by characterizing the channel according to a first-order autoregressive model of channel aging. Other aspects, embodiments, and features are also claimed and described.
