Abstract
The teachings herein disclose a receiving node and a related method for determining a channel estimate of a radio channel in a receiving node of a radio communication system. The method comprises 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 based on a digital sinc function.
