Analytical performance evaluation of various frequency reuse and scheduling schemes in cellular OFDMA networks
In this paper, we present an analytical solution to carry out performance analysis of various frequency reuse schemes in an OFDMA based cellular network. We study the performance in downlink in terms of signal to interference (SIR) ratio and total cell data rate. The latter is analyzed keeping in view three different scheduling schemes: equal data rate, equal bandwidth and opportunist. Analytic...
متن کاملAnalytical evaluation of various frequency reuse schemes in cellular OFDMA networks
In this paper, we present an analytical solution to carry out performance analysis of various frequency reuse schemes in an OFDMA based cellular network. We study the performance in downlink in terms of signal to interference (SIR) ratio and cellular capacity. Analytical models are proposed for integer frequency reuse (IFR), fractional frequency reuse (FFR) and two level power control (TLPC) sc...
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 کاملPerformance Evaluation of Energy-Efficient Game-Theoretic Resource Allocation Schemes in OFDMA Cellular Networks
In this paper, we study the performance of energy-efficient resource allocation schemes for multi-cell OFDMA networks based on Game Theory. These schemes have been evaluated in the literature; however, the evaluations have been done under different system models and simulation environments, making a fair comparison unfeasible. Hence, we first develop an appropriate system model for comparison. ...
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...
