Abstract
In this paper, time diversity is used as a technique to achieve EM resilience in a redundant communication channel that is subjected to multi-frequency electromagnetic disturbances. The geometry under study is subjected to strong incident fields consisting of random angles of incidence and polarizations. Time diversity is used as a measure to achieve fault tolerance in the system. The effects of a multi-harmonic Electromagnetic Interference (EMI) on the functional transmission signal inside a redundant three-channel system with time diversity is compared to the base case with no time diversity. The study shows that time diversity proves to be quite an effective measure to incorporate fault tolerance in redundant systems which are interfered by multi-frequency disturbances. The results reflect a clear improvement in performance in terms of the Bit Error Rates (BERs). Furthermore, results show that time diversity when suitably employed for a particular EMI disturbance can lead to optimal improvement in performance.
