A Multipath Detection Scheme Using SAT

By Mohamed El-tarhuni

Abstract

Abstract — This paper presents a new technique for multipath detection in wideband mobile radio systems. An intelligent search algorithm using Boolean Satisfiability (SAT) techniques is used to search for the multipath delays. The proposed algorithm finds the multipath components with high probability and hence allows the system to utilize the inherent diversity in these components to mitigate channel fading. Simulation results indicate that the system can achieve 90 % detection or higher of all paths at low signal-to-noise ratio under frequency-selective Rayleigh fading conditions. Keywords: Multipath detection; PN code acquisition; SAT. I
