Evaluation and optimization of active signal canceling for coexistence management in vehicular multistandard transceivers

authored by: Adrian Posselt, Marcel Welpot, Christian Böhm, Oliver Klemp, Bernd Geck
Abstract: In this paper the suitability of active signal canceling architectures for interference reduction and coexistence management within multistandard transceivers for automotive use is evaluated. After description of the key concepts of reconfigurable vehicular connectivity architectures, we discuss active signal cancellation as an approach to suppress interference from transmitted signals. The realized architecture yields attenuations of up to 60 dB for sine signals and sufficient suppression for typical signals with a non-zero bandwidth. Based on the analysis the system is evaluated for a typical coexistence scenario in which a terrestrial Digital Video Broadcast (DVB-T) signal is successfully received within a multistandard transceiver, which transmits an interfering and potentially blocking adjacent signal at the same time.
