| Popis: | Global System for Mobile communications-Railways (GSM-R) is now widely used for train-to-track radio communication. As for any radio communication system, non-intentional and intentional ElectroMagnetic Interference (EMI) can affect this track-to-train radio link. This paper studies the impact of low-power electromagnetic jammers on this communication. Firstly, experiments performed on a dedicated test bench are presented to evaluate the impact of selected jamming signals on a GSM-R radio communication. In certain jamming conditions, loss of connection can result. Then, a method to detect these jamming signals is presented. We considered and modelled a simplified GSM-R communication chain using a GMSK modulation. This was used to evaluate the impact of the jammer on the IQ constellation representation. As for the experimental part, the same interfering signals are applied. We then use the Error Vector Magnitude parameter to detect the presence of these jamming signals. Depending on the parameters of the modulation chain, we adapt our processing to detect the disturbance. A good detection of the jammed signal is obtained by analysing the EVM parameter while trying to detect these signals in an AWGN channel. |
