TECHNIQUE FOR CHANNEL ESTIMATION IN THE PRESENCE OF A SIGNAL PHASE DISCONTINUITY |
摘要 |
A technique for performing channel estimation based on a received signal comprising a first signal part and a second signal part in the presence of an unknown phase discontinuity between the first signal part and the second signal part is presented. A method implementation of this technique comprises providing a first channel parameter that is based on the first signal part, determining a second channel parameter based on the second signal part, estimating the phase discontinuity from the first channel parameter and the second channel parameter, updating the first channel parameter based on the estimated phase discontinuity, and determining a channel estimate based on the second signal part including performing channel estimation filtering using the updated first channel parameter as filter state information. |
