Interference Mitigation for the Future Aeronautical Communication System in the L-Band

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

Future Transportation

Greenhouse gas (GHG) emissions associated with transportation activities account for approximately 20 percent of all carbon dioxide (co2) emissions globally, making the transportation sector a major contributor to the current global warming. This book focuses on the latest advances in technologies aiming at the sustainable future transportation of people and goods. A reduction in burning fossil fuel and technological transitions are the main approaches toward sustainable future transportation. Particular attention is given to automobile technological transitions, bike sharing systems, supply chain digitalization, and transport performance monitoring and optimization, among others
