In this paper, a finite difference time domain (FDTD) method is applied to investigate capabilities of an ultrawide band (UWB) radar system to detect and locate a breast tumor. The first part of these investigations concerns ...

Considering environment factor and user movement randomness, a fuzzy decision tree based mobility prediction mechanism in mobile Internet is proposed. Based on the instance set, an initial fuzzy decision tree is built up ...

Gaining IP connectivity in mobile hotspots (e.g. public transport vehicles) through on-board local area networks and mobile gateways has recently attracted strong commercial and research interests. In this paper we propose ...

Future self-organising ad hoc networks (MANETs) will provide Internet access for ubiquitous wireless computing. In combination with cellular systems, e.g., B3G and 4G networks, self-organising networks will increase the ...

The achievable linear increase in multiple-input multipleoutput (MIMO) capacity is conditioned on sufficiently rich multipath" presenting in a wireless channel. Thus, the characterization of the resolvable multipaths in ...

In Cyclix Prefix OFDM (CP) systems, synchronization to the maximal multipath signal generally causes no problem, however, inter carrier interference (ICI) will be introduced in Zero-padding OFDM (ZP-OFDM) systems, e.g, ...

In this paper, a novel architecture for interworking of the Wireless Local Area Network (WLAN) and the Third Generation (3G) mobile cellular network is presented. This architecture is a hybrid model with additional controls ...

This paper outlines a novel iterative decoding technique for a rate K/N convolutional code based on recurrent neural network (RNN) with stopping criterion. The algorithm is introduced by describing the theoretical models ...

The WLAN and WiMAX standards are candidate solutions for a low-cost broadband wireless network. Interworking the two networks, using the network-layer QoS mechanisms of the Next Generation Network, will allow them to ...

This paper presents novel closed-form solutions to the sub-channel and power allocation problems of an orthogonal frequency division multiple access (OFDMA) system. We model the Rayleigh fading channel as a finite-state ...
