Performance Enhancement of Interference Alignment Techniques for MIMO Multi Cell Networks

Abstract

In order to increase the ability of a wireless communication network and to professionally diminish interference of the signals one of the hopeful technique is Interference alignment (IA). In this proposed work Multiple Input Multiple Output (MIMO) user of a network is considered in three folds where Gaussian Interference Broadcast Channel (GIBC) is as medium. In the first fold Transmit and Receive Beam forming vectors are designed, next to execute interference alignment using the Multiple Access Channel - Broadcast Channel Duality (MAC-BCD) when improving the capacity of users in each cell and at last to maintain equality among users Rate Balancing (RB) technique is proposed.
