Distributed Pre-Coder Design for Multi-Cell Joint Transmission with Interference Controlling

In coordinated multi cell communication inter cell Interference (ICI) is one key factor limiting the performance of the networks many solutions are proposed to overcome this problem such as inter cell Interference nullification (INFN) and signal to leakage ratio maximization (SLRM) In this paper one new pre coding method is proposed from the perspective of interference controlling (INFC) This method realizes the merits of INFN and SLRM and can flexible control interference level of networks so that it satisfies a preassigned level Numerical simulation shows that INFC is more suitable for the multi cell Joint transmission than INFN and SLRM
