Abstract: Provided are a virtual multi-antenna method for an orthogonal frequency division multiplexing (OFDM) system and an OFDM-based cellular system. The virtual multi-antenna method includes grouping sub-carriers in a frequency domain of an OFDM symbol and generating at least one group including G sub-carriers; and regarding the G sub-carriers included in the at least one group as multiple channels used in a multi-antenna technique and virtually applying the multi-antenna technique to the transmission and reception of the OFDM symbol. The virtual multi-antenna method can effectively reduce an interference signal and obtain the effects of a spatial division multiple access (SDMA) technique without physically using multiple antennas.

Abstract: The present invention relates to an apparatus and method for identifying a fake fingerprint by using impedance, which enables identification of a fingerprint or fake fingerprint by measuring an impedance value of a fake fingerprint made of silicon or gelatin. In the present invention, a fingerprint recognition module identifies, through a driver IC, an impedance value of an ultrasonic wave reflected from a finger and identifies a fake fingerprint on the basis of a changed impedance value, and determines a fake fingerprint by measuring an impedance value in an ultrasonic wave which is emitted from the fingerprint recognition module, collides with a fake fingerprint, and is then reflected therefrom. Therefore, the present invention can more accurately recognize a fingerprint than a conventional method of recognizing a fingerprint by distinguishing between x, y, z vectors thereof and, through accurate identification of a fake fingerprint, can prevent a harmful consequence which may be caused by an authentication of the fake fingerprint.
