Patent ID: 8160522

Claim:
A receiving apparatus of a Multiple Input Multiple Output (MIMO) system, the apparatus comprising: a clock generation/delay compensation unit configured to generate a clock; an antenna switching unit configured to temporally divide signals received through multiple antennas by performing switching according to the clock; a radio frequency (RF) chain to be shared configured to convert the temporally divided signals into baseband signals; an analog to digital converter (ADC) to be shared configured to convert the baseband signals into digital signals and output the digital signals according to the clock; an antenna signal separator configured to output the converted digital signals by separating the digital signals for the respective antennas according to the clock; and a modem configured to restore separated multiple antenna signals by using a MIMO algorithm and sequentially change delay levels of the clock based on a delay level whose bit error rate (BER) is less than a previously selected delay level after data decoding.
