Receiving apparatus and method for multiple-input multiple-output system

The present invention is a multiple-input multiple-output: relates to a receiving apparatus and method of the (Multiple Input Multiple Output MIMO) system, the receiver of the MIMO system, and the clock generation and delay compensation section that generates a clock, it received via multiple antennas for the signals to the above in accordance with the clock to switch to separate in time the antenna switching unit, RF chains, and the converted signal to convert into a baseband signal by sharing the RF chains for the signals separated by the temporal analog / by sharing: (ADC Analoge to digital converter) and converts into a digital signal, and separating the ADC outputs according to the converted signal to the clock, the signal converted into the digital signal by each receiving antenna in accordance with the clock-to-digital converter and the antenna output signal separation unit for, by applying the algorithm for MIMO multi-antenna the separated signal to restore the original signal It includes a modem and wherein the modem, and changing the delay level of the clock in sequence, to provide a modified delay level by the sequential parts of the clock generation and delay compensation, BER than the previous delay level to select the data after decoding ( Bit Error Rate), and select the delay level becomes small, and the clock generation and delay compensation unit, and to make the changes to delay level to the sequence to the clock provided to the ADC output to the ADC, the delay level by the modem when selected, characterized in that to apply the selected level of the delay on the clock provided to the ADC compensate for clock delays that occur between the antenna switching unit and the ADC.
