Abstract
In this paper, an OFDM based inlay system is considered, which is operated in the spectral gap between two adjacent channels of an already existing system in the L-band. The strong impact of pulsed interference from the existing L-band systems is mitigated by means of pulse blanking and clipping. When applying these well-known approaches to OFDM systems, the two main issues to be solved are the optimisation of the threshold for pulse blanking or clipping and the detection of the interference pulses in the received signal. Simulation results with the optimal threshold show that interference can be mitigated considerably. However, the performance of the interference-free case is not reached since the desired OFDM signal is impaired by pulse blanking and clipping.
