Software defined radio (SDR) is emerging as a powerful platform for future generation cellular systems, due to its capability to operate conforming to multiple mobile radio standards. Channelizer in an SDR operates at the highest sampling rate and hence a low complexity design is needed for the most computationally intensive part of the SDR receiver. The channel filters in the channelizer extra...

The availability of mobile information systems is being driven by the increasing demand to have information available for users at any time. As the availability of wireless devices increases, so will the load on available radio frequency resources. The radio frequency spectrum is limited, thus there will be a need to effectively manage these resources. This paper studies the application of the ...

This paper discusses the need for joint link level and system level simulations for thirdgeneration mobile radio systems and points out a way of implementing them in SDL. The simulation of third-generation mobile radio interfaces is a particular challenge to computational power. Complex systems are needed to support the demands of ATM services and high data of rates up to 2 Mbit/s in the UMTS b...

The massive deployment of cellular mobile radio networks claims attentions to their energy efficiency to favor both the eco-sustainability and the economic aspects. In this paper we study the impact of the power consumption in the design of mobile radio networks. We perform the analysis for GSM and LTE systems. The main aim is the analytical evaluation of the optimal cell radius accounting for ...

Wireless communication systems, both cellular and distributed multi-hop networks, require efficient utilization of scarce radio bandwidth and energy consumption costs. It is proposed to develop intelligent mobile location algorithms that utilize probabilistic estimates in order to minimize these costs. For cellular wireless systems, sequential paging algorithms have been developed for various d...

This paper considers two-dimensional interference-limited cellular radio systems. It introduces the shotgun cellular system that places base stations randomly and assigns channels randomly. Such systems are shown to provide lower bounds to cellular performance that are easy to compute, independent of shadow fading, and apply to a number of design scenarios. Traditional hexagonal systems provide...

In RFID (Radio Frequency IDentification) systems, a tag reader communicates with tags, reads their identification codes, and accesses their related database through network infrastructure. There are many research activities in RFID systems for industrial applications such as delivery, manufacturing, and so on, but there is few on mobile devices such as cellular phones and PDAs. This paper prese...

This paper deals with the automatic selection and configuration of base station sites for mobile cellular networks. An optimization framework based on simulated annealing is used for site selection and for base-station configuration. Realistic path-loss estimates incorporating terrain data are used. The configuration of each base station involves selecting antenna type, power control, azimuth, ...

This paper presents a c omparison of channel allocation schemes for mobile c ellular networks. Three schemes have been evaluated: Fixed Channel Allocation (FCA), Dynamic Channel Allocation (DCA) and Channel Allocation with Space a nd Time Variations (CA STV). The third scheme uses information about mobile users profiles for getting adaptability to traffic fluctuations. Results were obtained u s...

− Location Management is the procedure of keeping track of and locating Mobile Terminals (MT’s) in mobile radio communication system so that calls arriving for them can be routed correctly to their current location. The main aim of the Location Management is to track the MT’s using minimum overhead traffic. Since the radio bandwidth is a scarce resource in mobile radio communication systems, it...
