INTERFERENCE CANCELLATION UNDER NON-STATIONARY CONDITIONS Russian patent published in 2013 - IPC H04W56/00 H04B7/01 

FIELD: radio engineering, communication.

SUBSTANCE: method for timing and frequency synchronisation in a wireless system is provided. The method comprises steps of receiving a burst of symbols, selecting a subset of the burst of symbols, iteratively adjusting the subset of the burst of symbols by a plurality of timing offsets and calculating, for each timing offset, a first performance metric corresponding to the adjusted subset. The method further comprises steps of determining one of the plurality of timing offsets as a preferred timing offset based on the first performance metric thereof, iteratively rotating the subset of the burst of symbols by a plurality of frequency offsets and calculating, for each frequency offset, a second performance metric corresponding to the rotated subset, and determining one of the plurality of frequency offsets as a preferred frequency offset based on the second performance metric thereof.

EFFECT: cancellation of interference under non-stationary conditions.
