Paper Abstract

High power time-varying interference or jamming can severely disrupt wireless communication. Therefore, the technique of relevant interference mitigation is needed. Cooperative communication technique can organize a group of single-antenna systems in the same area at different locations as a distributed antenna array. Thus it can approximately achieve the diversity gain of regular multiple-antenna system. This paper is focused on cooperative communication for time-varying interference mitigation. Since some of traditional collaborative reception techniques have the constraint of requiring accurate estimation of SNR, an improvement of time-varying interference mitigation technique based on log-likelihood ratio (LLR) and jammer cancellation is proposed. The simulation results demonstrate that this new improved method enables communication in much more severe interference conditions.
