Localized monochromatic and pulsed waves in hyperbolic media
Ioannis M. Besieris and Amr M. Shaarawi
Consider a uniaxially anisotropic material with diagonal electric permittivity and magnetic permeability tensor elements εxx, εyy = εxx, εzz and μxx, μyy = μxx, μyy, respectively. If all four elements are positive, the dispersion relation is described by an ellipsoid. Within a certain frequency band, however, it may turn out that not all diagonal elements are positive and the dispersion relation is a hyperboloid. Under these conditions, the material is referred to as a hyperbolic medium. For simplicity, the discussion will be confined to a nonmagnetic material. Source-free, transverse magnetic electromagnetic fields in the frequency domain are expressed in terms of an appropriately defined Hertz vector potential equation governed by the equation © 2013 IEEE.

Opportunistic relaying with partial CSI and dynamic resource allocation
Islam A. El-Bakoury, Karim G. Seddik, and Ayman Elezabi
In this paper, we consider the problem of minimizing the source node average power required to achieve a certain transmission rate in the existence of a relay node. Some works have considered this problem with the assumption of perfect channel state information (CSI) at the source node. We consider more practical scenarios where the source does not know the channel between the relay and the destination, but receives one-bit feedback on the state of that channel and where a maximum power constraint exists at each transmitting node. We consider two relaying protocols, namely, the Multi-Hop (MH) and the Opportunistic Decode and Forward (ODF) protocols. We derive closed form expressions for the average power required under each protocol and compare their performances with the system that assumes perfect relay-destination channel knowledge at the source node. We find that the performance is close, indicating that one-bit feedback is very useful. We also derive an upper bound on the average power required by the MH protocol, and derive the outage probability expressions for the two protocols. © 2013 IEEE.

Novel architectures for squares, and sums of squares, of cross-correlations of bipolar sequences with applications to CDMA
Ayman Elezabi
This paper describes novel architectures for computing squares, and sums of squares, of cross-correlations of bipolar sequences. Both metrics are used in improved channel decoder metrics for CDMA systems, but also appear in other signal processing applications. The key idea is to compute outer products of each code vector with itself, and formulate the metrics so as to avoid explicit computation of cross-correlations. The expensive squaring unit is also eliminated. A detailed complexity analysis is carried out in which we demonstrate the advantages of these architectures. They also offer easier updates when there are incremental changes in the system. We also describe a few variations and special cases including short codes and asynchronous users, and point out further enhancements. © 2013 IEEE.

Levenberg-Marquardt and Conjugate Gradient methods applied to a high-order neural network
Islam El-Nabarawy, Ashraf M. Abdelbar, and Donald C. Wunsch
The HONEST network is a high order neural network that uses product units and adaptable exponential weights. In this paper, we explore the use of several learning methods with the HONEST network: Levenberg-Marquardt (LM), Conjugate Gradient (CG), Scaled Conjugate Gradient (a technique that combines LM and CG), and resilient propagation (RP). Using a benchmark of 19 datasets, we find that the first three methods mentioned produce lower average test set errors than RP to a statistically significant extent. © 2013 IEEE.
