Abstract
A method of performing channel estimation for a radio channel between a transmitter and a receiver of a radio access network, RAN comprises the step of performing an initial channel estimation () of the radio channel for each of a plurality of frequency ranges (), based on a radio signal received on the radio channel from the transmitter, the radio signal comprising a signal sequence () out of the set of signal sequences () in each of the frequency ranges (), to obtain an initial channel estimate () for each frequency range (), and applying a filter () to the initial channel estimates () for the frequency ranges (), a length () of the filter () in the frequency domain being greater than lengths of the frequency ranges (), to obtain a filtered channel estimate () for all subcarriers () in the respective one of the frequency ranges ().
