Spectrum is a limited and precious resource in wireless communications. Effective spectrum utilization becomes more and more important because of the expeditious increase of demand for wireless communications. In principle, the dual-polarization frequency reuse system, which employs two orthogonally polarized electromagnetic waves to carry information, can double the system capacity. However, t...

-The Long term evolution (LTE) is a latest technology standardized by 3 rd generation partnership project (3GPP) to fulfill the growing demands of the users like high data rates in downlink and uplink, low cost, high spectral efficiency etc. Due to the growing demand for high data rate there is need to focus on frequency reuse i.e. reuse-1 so that we can get complete spectrum with in a cell. Bu...

In recent years the Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution (LTE) networks have become rapid growing technologies in 4 Generation (4G) cellular wireless broadband systems. With the growing demand of these networks in everyday life, the service providers are offering different and better grade of services to satisfy the end users with increasing needs for ...

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...

In component based software engineering, the quality of the produced software directly depends on the quality of the components involved. As component quality measurement is gaining attention, discovery of good quality components is an advancing topic. This paper presents a new metric for component assessment. The contribution of this paper is threefold. First, we define the Reuse Frequency of ...

a novel distributed frequency allocation scheme named as exponential distribution based frequency allocation (EDFA) is proposed in Fractional Frequency Reuse (FFR) aided OFDMA networks. EDFA has a flexible adjustment between fairness and throughput. Simulation results demonstrate that compared to the proportional fairness (PF) allocation and equal rate allocation (ERA) schemes, EDFA could achie...
