Householder-based anti-jamming navigation receiver structures

Abstract

This paper addresses the problem of mitigating intentional jumming in navigution receivers using sinart arztetmns and space-time processing. Three differenl anti-jantining receiver strucrrires etuplo.ving cavipirru~iunullv eflcient miiltistuge Wiener j l t e r processing und Holcseholtkr transJonns are ~ireseii~eil. Space-time processing provides srffcieiit number of degrees of freedom for cancelling large nitinher of wideband jammers. The pe&rtnances of the receiver struditres in tenm of signal-to-inle~erence plus noise rutiu (SINR) uiid bit error rule (BER) are compared in sb?rulurion using denrancling junrmiiig scenarios. 7'he robustness and cornputalionul cornple.rit~v of the tnethods are considered as well.
