<p>A method (50) of operating a communications receiver (20). The method receives a communications signal (10) which is transmitted via a channel, where the communications signal comprises received known pilot data (DP) and received information data (DI), the known pilot data and information data being sequentially transmitted. The method then estimates a first channel impulse response (52) for the channel, wherein the first channel impulse response is in response to the received pilot data. Next, the method determines (54) a group of estimated information data in response to the first channel impulse response. Next, the method estimates a second channel impulse response (56) for the channel in response to the estimated information data. Thereafter, the method forms (56) a combined channel impulse response for the channel. The combined channel impulse response is in response to the estimated information data and the known pilot. The combined channel impulse response is in response to a combination of a first weight applied to the first channel impulse response and a second weight applied to the second channel impulse response, wherein the first weight differs from the second weight. <IMAGE></p> |
