Frequency reuse in 3GPP-LTE downlink cellular system

Abstract

The purpose of the study was to implement a frequency reuse in 3GPP-LTE downlink cellular system which was to be used as the main measurement and as analysis tool for interference mitigation and to evaluate the performance for various conditions enabling the efficient deployment and optimization of femto cells on multi-tier networks. The Mat Lab Vienna LTE simulator was used to analyses the degrading impact of interference on channel capacity when Femto-cells are deployed over a Macro-cell network to buttress the need for interference mitigation techniques in modern wireless communication networks. It was seen that Femto-cells provide a better solution in terms of benefits experienced by both the CSPs and the subscribers such as ease of deployment and cost effectiveness. As a result of the Femto-cells operating on the same licensed band used by the Microcells, interference between the two tiers is inevitable if proper mitigation technique is not employed. The various categories of interference in multi-tier heterogeneous radio access networks are given with emphasis on Macro-cell overlaid with Femto-cells on indoor environment. To carry on the research, however there were various research and information gathering techniques such as desk research ,Mat Lab simulations and in addition the supervisors involvement in order to come up with the complete systems.
