<p>A method of signal processing and a signal processor for a receiver for OFDM encoded digital signals. OFDM encoded digital signals are transmitted as data symbol subcarriers in several frequency channels. A subset of the sub-carriers is in the form of pilot subcarriers having a pilot value (ap) known to the receiver. The method comprises estimation of a channel transfer function (H) and a derivative of the channel transfer function (H') by means of a channel estimation scheme from a received signal (y). Then, an estimation of data (a) is performed from the received signal (y) and the channel transfer function (H). Finally, an estimation of a cleaned received signal (y2) is performed from the data (a), the derivative of the channel transfer function (H') and the received signal (y) by removal of inter-carrier interference (ICI), by taking into account at least one of a previous and a future OFDM symbol, followed by an iteration of the above-mentioned estimations.</p> |
