Frequency Reuse In 3gpp-Lte Downlink Celluar 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
