Inter-cell interference (ICI) is responsible for user throughput degradation and especially for users found near cell border which additionally experience serious path-losses. Efficient methods for ICI mitigation are ICI coordination (ICIC) schemes which allocate certain resources among users in different cells. In this paper we propose a decentralized ICIC scheme in order to mitigate the ICI and...
Due to the frequency reuse, Inter-cell interference is a main reason for performances degradation of cellular systems. Fractional frequency reuse is one of the several methods supported by 3GPP Long Term Evolutions systems for Inter-cell interference cancellation. The influence of fractional frequency reuse on system performances is already studied in the literature but mostly by computer simulations...
In this paper the impact of the overlay of CDMA2000 1x-EVDO and CDMA2000 cellular systems in terms of throughput is investigated. Currently, the 3G cellular systems furthermore to provide only voice services are focusing to offer a variety of data applications such as VoIP, video, telephony, wireless gaming, and push-to-talk (PTT), along with a high demand of downlink intensive applications. The result...
Smart antenna is recognized as promising technologies for higher user capacity in 3G wireless networks by effectively reducing multipath and co-channel interference. Advent of powerful, low-cost, digital processing components and the development of software-based techniques has made smart antenna systems a practical reality for both base station and mobile station of a cellular communications systems...
