Interference Mitigation Optimal Dynamic Fractional Frequency Reuse (OD-FFR) Scheme in LTE Networks
Fractional Frequency Reuse is an interference mitigation technique well suited for OFDMA system where the cell region is partitioned into two: inner cell region and outer cell region. In this paper we proposed an interference mitigation technique in LTE OFDMA femtocell system using Fractional Frequency Reuse (FFR) also system in order to improve performance of the system resource allocation is ...
متن کاملInter-cell Interference Mitigation through Flexible Resource Reuse in OFDMA based Communication Networks
The inter-cell interference problem is a key issue in OFDMA-based mobile cellular networks. In order to deal with this problem, several flexible radio resource reuse schemes for the downlink are examined in this paper. The goal is to improve the cell edge throughput as well as the average cell throughput, compared to a network with frequency reuse factor 1. The cell capacity under those reuse s...
متن کاملDynamic Fractional Frequency Reuse in OFDMA systems
While OFDMA orthogonalizes users within a cell, out-of-cell interference avoidance is a primary concern in the practical implementation of OFDMA systems. This project explores one of the key ideas towards limiting the harmful effects of out-of-cell interference: fractional frequency reuse (FFR) (1). We first explore the idea of frequency reuse and introduce FFR. Then, we discuss the algorithm f...
متن کاملA Novel Frequency Planning for Femtocells in OFDMA-Based Cellular Networks Using Fractional Frequency Reuse
Femtocells are expected to be one of the emerging technologies for next generation communication systems. For successful deployment of femtocells in the pre-existing macrocell networks, there are some challenges such as the cell planning for interference management, handoff, and power control. In this paper, we focus on frequency planning which can provide interference avoidance for the co-exis...
