Multiple Antenna Communication Systems using Space-Time Line Code

摘要

Disclosed is a multiple-antenna communication system using space-time line coding. According to an embodiment of the present invention, a transmission device comprises: a plurality of antennas transmitting and receiving a wireless signal; a space-time line code (STLC) encoder processing a transmission symbol in a space-time linear coding scheme and outputting a plurality of coded signals for transmission at different times; an artificial noise signal generator for generating an artificial noise signal removed by STLC decoding; and a current allocation processor for allocating power to the coded signals and the artificial noise signal to generate transmission signals and to sequentially transmit the transmission signals through the plurality of antennas.
