Different Methods Based on CSI for Interference Reduction in MIMO system

Abstract

Nowadays, the interference is the major problem faced in wireless communication systems, mostly in urban cities of developed countries. Due to this various interference avoidance and interference cancellation schemes are introduced. In this paper we are going to elaborate schemes for interference cancellation such as DPC(Dirty paper coding) and BF-JD(Beam forming with joint decoding). The interference affects the MIMO system model and to reduce this interference the channel state information is estimated both at the transmitter and the receiver. So, this paper compares the performance in both cases when the channel state information is perfect as well as imperfect. For MIMO system by using the decoding techniques DPC (Dirty paper coding) and BF-JD(Beamforming with joint decoding).
