Abstract:
A method of operating a communications receiver, comprising the steps of:receiving a communications signal which is transmitted via a channel, the communications signal comprising received known pilot data and received information data, the known pilot data and information data being sequentially transmitted; first, estimating a first channel impulse response for the channel, wherein the first channel impulse response is in response to the received known pilot data; second, determining a group of estimated information data in response to the first channel impulse response; third, estimating a second channel impulse response for the channel, wherein the second channel impulse response is in response to the group of estimated information data; and fourth, forming a combined channel impulse response for the channel, wherein 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 received known pilot data has a first power; wherein the received information data has a second power; and wherein the first weight differs from the second weight in response to a relationship between the first power and the second power.
