Apparatus and method for reception in multi-input multi-output system
Provided are an apparatus and method for reception in a MIMO system. An apparatus for calculating a signal weight, includes: at least two multiplexers configured to receive, a data stream corresponding to a weight inputted and multiplex the received data stream prior to output; a multiplexing control unit configured to control the outputs of the respective multiplexers and provide a clock of a predetermined rate and a clock of a double rate two times higher than the predetermined rate; a first multiplier configured to receive multiplexed data outputted from the respective multiplexers and multiply the multiplexed data; a first storage unit configured to latch the multiplication result of the first multiplier by the double-rate clock prior to output; an adder configured to add the output of the first storage unit and the output of the first multiplier; and a second storage unit configured to latch the addition.
