Abstract

A method in a wireless receiver for estimating a channel. The method includes receiving a signal comprising a plurality of transmission layers, each layer having at least one reference signal according to a predefined reference signal sequence; determining a window size for performing a sampling operation, wherein the operation is performed in a transformed domain of the received signal; selecting a channel tap length, from a range of channel tap lengths, wherein the selection is based on the window size, a noise mean and a noise variance. The channel estimation is performed from a reference signal sequence for the at least one reference signal and based on samples corresponding to the selected channel tap length.
