Interference Mitigation using Alignment Technique for Broadcasting Channel Scenario
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 2
Abstract
The technique to mitigate interference in the channel is very essential to maintain efficient signal transmission. Interference Alignment (IA) deals to mitigate interference and to enhance system efficiency of a wireless communication network. We deal with interference alignment scheme for a network with multiple cells and multiple multiple-input and multipleoutput users under a Gaussian interference broadcast channel scenario. At first we go for grouping method already known to a multiple-cells scenario and jointly design transmit and receiver beamforming vectors using a closed form expression without iterative computation. Then we go for a new approach using the principle of multiple access channel (MAC) - broadcast channel (BC) duality to perform interference alignment while maximizing capacity of users in each cell.
