Multiple Antenna Communication Systems using Space-Time Line Code

摘要

A multi-antenna communication system using space-time coding is disclosed. A transmitting apparatus according to an embodiment of the present invention includes a plurality of antennas for transmitting and receiving radio signals, a Space-Time (STLC) system for 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 to be removed by STLC decoding, and a transmitter for generating a transmission signal by allocating power to the coded signal and the artificial noise signal, and transmitting the transmission signal through the plurality of antennas And a power allocation processor for sequentially transmitting the power control signal.
