Abstract
In a method for estimating a channel at a receiver in a wireless communications network, the receiver obtains channel model parameters for a received signal based on raw channel estimates for the received signal, where each raw channel estimate corresponds to an antenna at the receiver. The receiver combines, for each of a plurality of contiguous subcarriers in the wireless communications network, the channel model parameters to generate a first plurality of combined channel model parameters. The receiver then chooses a first set of indices corresponding to combined channel model parameters from among the first plurality of combined channel model parameters having magnitudes passing a combined channel model parameter threshold. The receiver then estimates the channel in a sparse domain based on the first set of indices.
