Abstract
A receiver and a method for channel estimation, the method includes calculating at least one initial channel estimate; characterized by calculating an estimate of the channel based upon a mathematical relationship between a first group of pilot subcarriers and a second group of pilot subcarriers;whereas a difference between locations of pilot subcarriers of the first group and locations of corresponding pilot subcarriers of the second group is substantially constant; and at least one of the following conditions are fulfilled: (i) pilot subcarriers that belong to the same group of subcarriers are non-evenly spaced in a frequency domain, (ii) a pilot subcarrier of the first group and a corresponding pilot subcarrier of the second group are proximate to each other in the frequency domain.
