Abstract
Disclosed is a method for compensating phase noise. A symbol comprising one or more data sub-symbols and one or more pilot sub-symbols is received (). A sequence of first phase noise estimates is obtained () based at least partly on the one or more pilot sub-symbols. A first filter is used to obtain () a first sequence of filtered phase noise estimates from at least a subset of the one or more data sub-symbols based at least partly on the sequence of first phase noise estimates. The first sequence of filtered phase noise estimates is stored (). Phase noise compensation is applied () to the one or more data sub-symbols based at least partly on the first sequence of filtered phase noise estimates.
