Analysis and Investigation of Interference Rejection Combining Technique inAdvancedLong Term Evolution (LTE)

Abstract

One of the main problems which is happened in long term evolution Advanced system (LTE-A) or 4G, is interference In this thesis Interference Rejection Combining (IRC) technique have been applying to reduce interference, especially That is happenings between cell edge or inter cell interference , IRC is a method to increase the channel quality by using receiver antenna diversity and interference rejection. IRC is able to suppress the interfering signal and thereby increase the quality of the received signal. This situation, is typical for high capacity areas (urban areas)or low capacity areas(suburban areas) where tighter frequency reuse is in place (IRC) is comparing with other algorithms in reducing interference, through the results (by investigation and analyzes) it has been found that (IRC) is less (BER)Than other algorithms and this is lead to increase throughput and capacity of system
