Comparative Evaluation of Fractional Frequency Reuse (ffr) and Traditional Frequency Reuse in 3gpp-lte Downlink
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...
متن کاملAnalytical Evaluation of Fractional Frequency Reuse for Heterogeneous Cellular Networks
Interference management techniques are critical to the performance of heterogeneous cellular networks, which will have dense and overlapping coverage areas, and experience high levels of interference. Fractional frequency reuse (FFR) is an attractive interference management technique due to its low complexity and overhead, and significant coverage improvement for low-percentile (cell-edge) user...
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...
