Claim Text:
1. Equalizing method in a receiver of a cellular wireless communication system, the method comprising: receiving at least one radio signal comprising a plurality of resource elements; obtaining interference information associated with the plurality of resource elements; extracting resource elements from the plurality of resource elements carrying data into a set based on the interference information, the set including resource elements affected by interference from among resource elements of the plurality of resource elements unaffected by interference; dividing the resource elements in the set into one or more sub-sets comprising T number of resource elements, the one or more sub-sets being formed to correlate with interference; filtering the resource elements in said one or more sub-sets using a balanced whitening and energy focusing filter W and obtaining filtered resource elements y; and equalizing the filtered resource elements y using at least one detector configured to handle L Multiple Input Multiple Output (MIMO) layers in the receiver of the cellular wireless communication system from among the plurality of resource elements including the resource elements unaffected by interference which are comprised in radio signals of different channels and pilot symbols received over a MIMO radio channel, the at least one detector performs the equalizing of the filtered resource elements y.
