초록

Instead of existing precoding techniques that eliminate severe inter-cell interference, in this paper, a new IA( Interference Alignment ) based precoding scheme that deliberately creates the exploitable interference is proposed to improve the robustness of the transmission in CoMP( Coordinate MultiPoint ) systems. The precoding scheme is applied to PSK( Phase Shift Keying ) modulated symbol, and the each of precoded symbols acts positively to all receivers.
