ABSTRACT:
A receiving method and a receiver comprising circuit elements that are arranged to calculate estimates for parameters of a received signal in two or more stages, for processing the signal iteratively by means of an observation time-slot of a given length and containing a plurality of samples, and for sliding the observation time-slot over the received samples. In order to avoid complicated matrix operations, the receiver comprises circuit elements for sliding the observation time-slot in such a way that successive observation time-slots partly overlap, and for employing, upon calculating the estimates and decisions of parameters in each observation time-slot, estimates provided by the previous observation time-slot as initial values for those samples that fall within the previous observation time-slot, and estimates provided by the previous stage for those samples that do not fall within the previous observation time-slot.
