A MATLAB-based one-way and two-way split-step parabolic equation software tool (PETOOL) has been developed with a user-friendly graphical user interface (GUI) for the analysis and visualization of radio-wave propagation over variable terrain and through homogeneous and inhomogeneous atmosphere. The tool has a unique feature over existing one-way parabolic equation (PE)-based codes, because it utilizes the two-way split-step parabolic equation (SSPE) approach with wide-angle propagator, which is a recursive forward-backward algorithm to incorporate both forward and backward waves into the solution in the presence of variable terrain. First, the formulation of the classical one-way SSPE and the relatively-novel two-way SSPE is presented, with particular emphasis on their capabilities and the limitations. Next, the structure and the GUI capabilities of the PETOOL software tool are discussed in detail. The calibration of PETOOL is performed and demonstrated via analytical comparisons and/or representative canonical tests performed against the Geometric Optic (GO) + Uniform Theory of Diffraction (UTD). The tool can be used for research and/or educational purposes to investigate the effects of a variety of user-defined terrain and range-dependent refractivity profiles in electromagnetic wave propagation.

Two way split step parabolic equation algorithm for tropospheric propagation Tests and comparisons ÖZGÜN, ÖZLEM; APAYDIN, GÖKHAN; Kuzuoğlu, Mustafa; SEVGİ, LEVENT (2010-08-25) This paper introduces a two-way split-step parabolic equation propagation tool (2W-SSPE), which is capable of handling both forward and backward scattered waves during groundwave propagation over an irregular terrain, through inhomogeneous atmosphere. The algorithm is calibrated and tested against reference data obtained with the help of image method and the Geometric Optic (GO) + Uniform Theory of Diffraction (UTD).
Recursive Two-Way Parabolic Equation Approach for Modeling Terrain Effects in Tropospheric Propagation Ozgun, Ozlem (2009-09-01) The Fourier split-step method is a one-way marching-type algorithm to efficiently solve the parabolic equation for modeling electromagnetic propagation in troposphere. The main drawback of this method is that it characterizes only forward-propagating waves, and neglects backward-propagating waves, which become important especially in the presence of irregular surfaces. Although ground reflecting boundaries are inherently incorporated into the split-step algorithm, irregular surfaces (such as sharp edges) in...
Real-Time Moving Target Search Undeger, Cagatay; Polat, Faruk (2007-11-23) In this paper, we propose a real-time moving target search algorithm for dynamic and partially observable environments, modeled as grid world. The proposed algorithm, Real-time Moving Target Evaluation Search (MTES), is able to detect the closed directions around the agent, and determine the best direction that avoids the nearby obstacles, leading to a moving target which is assumed to be escaping almost optimally. We compared our proposal with Moving Target Search (NITS) and observed a significant improvem...
GF (2M) multiplier implementation on a partially reconfigurable FPGA Kocalar, Gizem; Bazlamaçcı, Cüneyt Fehmi; Department of Electrical and Electronics Engineering (2015) The thesis aims to design and implement a Galois ﬁeld multiplier IP block that adapts to changing input trafﬁc conditions, using partial reconﬁguration feature of FPGAs. Two different multiplier blocks are used for high and low trafﬁc rates. First, an area efﬁcient multiplier block with small area utilization and low power consumption is designed by using splitting type multiplication algorithms. Second, a high performance multiplier IP block with higher resource consumption but better time performance is d...
MIPS Extension for a TCAM Based Parallel Architecture for Fast IP Lookup Erdem, Oguzhan; Bazlamaçcı, Cüneyt Fehmi (2009-09-16) This paper discusses the feasibility of the use of minimum independent prefix set (MIPS) algorithm in a ternary content addressable memory (TCAM) based parallel architecture proposed for high speed packet switching. MIPS algorithm is proposed earlier to transform a forwarding table into one that contains the minimum independent prefix set. In this paper we propose MIPS algorithm to be integrated into a TCAM based parallel IP lookup engine. We first analyze the table compression performance of the MIPS algor...
