Capacity is one of the significant factors in determining the performance of any cellular system. However, the capacity is limited by the interference. In cellular systems, the major source of interference is the Co-Channel Interference(CCI). In this paper, an analytical method is proposed to evaluate the erlang capacity of 3G WCDMA systems under CCI and(More)
The advent of Global Positioning System (GPS) has revolutionized the field of navigation particularly in the field of civil aviation sector. The accuracy of GPS system is affected by several factors. One such factor is satellite Geometry, which represents the geometric locations of the GPS satellites as seen by GPS receiver. This plays a very important role(More)
This paper proposes novel heuristic algorithm called gravitational search algorithm (GSA) to speech enhancement. Stochastic and heuristic algorithms like particle swarm optimization (PSO) and some of its variants have been adapted to the field of speech enhancement in recent years. Although standard PSO (SPSO) finds good solutions, it suffers from the(More)
In this paper we have investigated compact printed semicircular disc monopole antenna, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular we have simulated very compact semicircular disc monopole antennas for UWB communication. Simple rectangular microstrip line is used for feeding the printed monopole(More)
The GSM cellular system is one of the most popular 2G/2.5G/2.75G digital cellular telecommunications systems, which is widely used throughout the world. One of the most attractive features of GSM cellular system is handoff. It is the process of continuation of an active call when the mobile is moving from one cell to another without call termination.(More)
