This paper presents a novel technique - Multi-Channel Ratio (MCR) Decoding, which aims at providing an anti-jamming wireless communication capability for multi-antenna wireless devices. The basic idea of MCR decoding is to fully leverage the repeated preamble signals and the multi-channel characteristics in MIMO communications to detect and recover the desired transmission signals under constant and reactive jamming attacks. This paper also reports the analysis, implementation, and experimental evaluations of MCR decoding on a software-defined radio platform - GNURadio and USRP, which show that the proposed MCR decoding can detect the desired transmission reliably under the jamming attack and remove jamming signals effectively in the real world environment.
