ABSTRACT:
A method is disclosed that includes channel estimation for a multi-carrier modulation of a plurality of subcarriers. The method includes performing a first channel estimation to obtain a first estimate of a channel based on a received signal. The method further includes suppressing a portion of elements of the first estimate of the channel to obtain a suppressed estimate of the channel. The method also includes multiplying the suppressed estimate of the channel by a first matrix to obtain a delay restricted estimate of the channel.
