Mitigation of Co-channel Interference in Long Term Evolution Using Fractional Frequency Reuse Scheme
ثبت نشده
چکیده
Co-channel interference in Long Term Evolution (LTE) cellular network is caused due to usage of same frequencies between the neighboring cells at the same region. Here the term co-channel interference is otherwise known as inter-cell interference. It is important to mitigate co-channel interference at micro-cells inorder to improve the communication performance of the cellular network. In this paper, we propose a fractional frequency reuse approach for microcells to mitigate the co-channel interference. In this approach, the cell is partitioned into inner region & outer region and selects the optimal frequency allocation for each region in the cell to enhance the overall throughput and user satisfaction.

Selecting the Optimal Fractional Frequency Reuse Scheme in Long Term Evolution Networks
Long Term Evolution (LTE) networks offer high capacity and are specified and designed to accommodate small, high performance, power-efficient end-user devices. One limiting factor that influences LTE performance is the interference from neighbouring cells, the so called Inter-Cell Interference (ICI). The investigation of ICI mitigation techniques has become a key focus area in achieving dense s...

3 Generation Partnership Project Long Term Evolution (3GPP-LTE) is focusing towards aggressive frequency reuse i.e. reuse of 1 so that we can get maximum number (all available spectrum) within a cell. Now, the major hindrance is co-channel interference which increases dramatically due to nearby adjacent co-channel cell and most especially for cell edge users. Traditional frequency reuse concept...

For satisfying the need of increasing number of users, their demands for the services and to provide enhanced indoor coverage, Long Term Evolution (LTE) has developed small cellular base stations called Femtocells. However, limited spectrum Availability in the cellular networks causes severe interference Issues in the neighboring femtocell users transmitting in the same radio band. In densely d...
متن کاملThroughput Performance for Heterogeneous LTE Network by Using Fractional Frequency Reuse Method
In cellular system, Fractional Frequency Reuse (FFR) is partition each cell into two regions which are the cell center region and cell edge region. The dissimilar frequency band is owed to each region in cell. The FFR method may reduce channel interference and achieve large system capacity and hence increases the throughput. Long Term Evolution (LTE) has developed a femtocell for indoor coverag...
متن کاملFractional Frequency Reuse with Ordering to Increase Capacity of OFDM Systems
We present a novel frequency partitioning technique of fractional frequency reuse (FFR) that reduces the effect of co-channel interference and increases the capacity of OFDM systems. The usable sub-channel sets are classified into the common sub-channel sets for all cells and the dedicated sub-channel sets for specific cell types in FFR. The proposed fractional frequency reuse with ordering sch...
