The approaching 4G (fourth generation) mobile communication systems are projected to solve still-remaining problems of 3G (third generation) systems and to provide a wide variety of new services, from high-quality voice to high-definition video to high-data-rate wireless

Game dynamics and cost of learning in heterogeneous 4G networks
free download

In this paper, we study game dynamics and learning schemes for heterogeneous 4G networks. We introduce a novel learning scheme called cost-to-learn that incorporates the cost to switch, the switching delay, and the cost of changing to a new action and, captures

A 477mW NoC-based digital baseband for MIMO 4G SDR
free download

Baseband processing for advanced Telecom applications have to face two contradictory issues . The first one is the flexibility required, with the exploding number of modes for a single protocol (eg 63 for 3GPP-LTE), the number of protocols to be supported by a single

Adaptive interleave-division multiple access-a potential air interface for 4G bearer services and wireless LANs
free download

A novel adaptive modulation/channel coding scheme based on interleave-division multiple access (IDMA) in conjunction with reliability estimation is proposed. Unlike conventional adaptive modulation/channel coding schemes where the data rate is changed by switching

Trends in the path to 4G
free download

The integration and interoperability of diverse technologies, along with new truly broadband wireless innovations and intelligent, user oriented services will lead towards a new generation of heterogeneous wireless networks, which has already been called 4G . It is This article gives an overview on the state of the art of potential security issues that occur in the deployment of the LTE/SAE (Long Term Evolution/System Architecture Evolution) protocol in the emerging 4G wireless technologies. Security concerns and challenges on

Always best connected enabled 4G wireless world
free download

The evolution of a fully Always Best Connected ABC enabled fourth generation wireless world, 4GWW, paradigm is addressed in this paper. It addresses the subjective and objective nature of the ABC concept from the viewpoints of the various wireless network

Evolution of the air interface of cellular communications systems toward 4G realization
free download

Early cellular networks used analog frequency modulation for voice communication and frequency division multiple access to accommodate multiple users. Despite their utility, these networks were often unstable and provided poor quality. Over the past 25 years, robust

LTE Advanced: The 4G mobile broadband technology
free download

By the design and optimization of upcoming radio access techniques and a further evolution of the existing system, the Third Generation Partnership Project (3GPP) had laid down the foundations of the future Long Term Evolution (LTE) advanced standards-the 3GPP

Evolution of Mobile Communications: from 1G to 4G
free download

Today, mobile communications play a central role in the voice/data network arena. With the deployment of mass scale 3G just around the corner, new directions are already being researched. In this paper we address the evolution of mobile communications, from its first

A robust optimal rate allocation algorithm and pricing policy for hybrid traffic in 4G -LTE
free download

In this paper, we consider resource allocation opti-mization problem in the fourth generation long-term evolution ( 4G -LTE) with elastic and inelastic real-time traffic. Mobile users are running either delay-tolerant or real-time applications. The users applications are A Multiple-input-multiple-output(MIMO) rectangular dielectric resonator antenna (RDRA) for 2.6 GHz long term evolution (LTE) applications is investigated and presented. Two orthogonal modes of the RDRA are excited by using two different feed mechanisms: CPW

Cellular multihop communications: infrastructure-based relay network architecture for 4G wireless systems
free download

In cellular communications, the amount of total available resources (frequency-time plane) and the QoS requirements jointly determine the capacity per cell. And, the transmit power (especially in the reverse-link) and the propagation conditions determine the cell size. If the
