A method for determining a channel estimate of a radio channel in a receiving node of a radio communication system, the method comprising: - calculating a matched filter channel estimate based on a known reference signal and a received reference signal in a frequency domain, - transforming the matched filter channel estimate into an over-sampled transform domain channel estimate, - applying a window to the over-sampled transform domain channel estimate to achieve a windowed transform domain channel estimate, - transforming the windowed transform domain channel estimate into a frequency domain channel estimate, and - compensating for a bias in the over-sampled frequency domain channel estimate characterized in that the compensating is based on a digital sinc function, wherein the compensating for a bias comprises: calculating de-biasing values based on the following equation: B k = 1 N c ⁢ K os ∑ kʹ = 0 N c - 1 sin π ⁢ k - kʹ ⁢ m R - m L + 1 N c ⁢ K os sin π ⁢ k - kʹ N c ⁢ K os ⁢ e - j ⁢ π ⁢ k - kʹ ⁢ m R + m L - 2 ⁢ m 0 k N c ⁢ K os wherein k and k' are sub-carrier indices, N c is the number of sub-carriers for which the channel estimate is determined, K os is the over-sampling factor, m R is the right channel tap index of the applied window, m L is the left channel tap index of the applied window, and m 0 ( k) is the group delay of the radio channel as function of sub-carrier index k, and compensating for the bias in the over-sampled frequency domain channel estimate based on the calculated de-biasing values. - calculating a matched filter channel estimate based on a known reference signal and a received reference signal in a frequency domain, - transforming the matched filter channel estimate into an over-sampled transform domain channel estimate, - applying a window to the over-sampled transform domain channel estimate to achieve a windowed transform domain channel estimate, - transforming the windowed transform domain channel estimate into a frequency domain channel estimate, and - compensating for a bias in the over-sampled frequency domain channel estimate characterized in that the compensating is based on a digital sinc function, wherein the compensating for a bias comprises: calculating de-biasing values based on the following equation: B k = 1 N c ⁢ K os ∑ kʹ = 0 N c - 1 sin π ⁢ k - kʹ ⁢ m R - m L + 1 N c ⁢ K os sin π ⁢ k - kʹ N c ⁢ K os ⁢ e - j ⁢ π ⁢ k - kʹ ⁢ m R + m L - 2 ⁢ m 0 k N c ⁢ K os wherein k and k' are sub-carrier indices, N c is the number of sub-carriers for which the channel estimate is determined, K os is the over-sampling factor, m R is the right channel tap index of the applied window, m L is the left channel tap index of the applied window, and m 0 ( k) is the group delay of the radio channel as function of sub-carrier index k, and compensating for the bias in the over-sampled frequency domain channel estimate based on the calculated de-biasing values. calculating de-biasing values based on the following equation: B k = 1 N c ⁢ K os ∑ kʹ = 0 N c - 1 sin π ⁢ k - kʹ ⁢ m R - m L + 1 N c ⁢ K os sin π ⁢ k - kʹ N c ⁢ K os ⁢ e - j ⁢ π ⁢ k - kʹ ⁢ m R + m L - 2 ⁢ m 0 k N c ⁢ K os wherein k and k' are sub-carrier indices, N c is the number of sub-carriers for which the channel estimate is determined, K os is the over-sampling factor, m R is the right channel tap index of the applied window, m L is the left channel tap index of the applied window, and m 0 ( k) is the group delay of the radio channel as function of sub-carrier index k, and compensating for the bias in the over-sampled frequency domain channel estimate based on the calculated de-biasing values.
