Abstract
An apparatus and a method are provided including a parameter estimator, a controller, an initial channel estimator, and a channel estimator. The parameter estimator configured to estimate parameters related to a channel. The controller configured to select one of channel environments based on the parameters, and generate a control signal corresponding to the selected channel environment. The initial channel estimator configured to estimate an initial channel based on the control signal. The channel estimator configured to estimate a channel of remaining resource blocks, excluding resource blocks corresponding to a pilot signal, from among resource blocks, based on the initial channel and the control signal.
