Combining 2oo3 Voting and Hamming Error Correction to Reduce the Occurrence of False Negatives in Wired Communication Lines under Continuous-Wave Electromagnetic Disturbances

In this paper, a multi-layer scheme to increase the safety of wire communication lines against electromagnetic interference is evaluated. The multi-layer approach consists of a voter based on three wired communication lines which are or are not optimally time diverse. On a second layer, Hamming encoding and decoding is implemented. Each separate technique and possi-ble multi-layer approach is evaluated in simulation under a wide range of single-frequency electromagnetic disturbances. A new way of combining both layers is introduced, i.e. using warnings of the first layer in the second layer is presented. The results show an increase in the safety of the communication system (i.e. reducing the number of false negatives) when combining multiple layers. As a bonus, the availability of the communication system can also be increased by combining multiple layers, if one chooses to.
