Abstract
A processor (110) is disclosed for processing a plurality of Fourier-transformed instances of a symbol, each instance being comprised in one of a plurality of frequency-divided multiplexed subcarriers, said processor being arranged to estimate, for each instance, the channel gain and the inter-carrier interference contribution to said symbol from neighboring subcarriers due to a time-varying channel response of the received signal, and combine the instances into a single representation of said symbol based on the estimated channel gain and the inter-carrier interference contributions. A receiver comprising such a processor and a method for processing such signals are also disclosed.
