Beam processing architecture in wireless communication systems
A method, a system, and a computer program product for processing of data signals in a wireless communication system. An input data signal having a plurality of portions of antenna carrier symbols is received. One or more beam weights are assigned to one or more antenna carrier symbols in each portion in the plurality of portions of antenna carrier symbols. Each antenna carrier symbol is processed using at least one assigned beam weight in the one or more assigned beam weights to generate a processed portion of antenna carrier symbols. The processed portion of antenna carrier symbols is stored while performing the processing of another portion of antenna carrier symbols in the plurality of portions of antenna carrier symbols. The stored processed portion of antenna carrier symbols is combined with the processed another portion of antenna carrier symbols to generate an output data signal.
