The engineering world is mostly made up from the reuse, reinvention or reapplication of old knowledge, rather than single groundbreaking new findings. Each small advance contributes to human knowledge with an impact that can’t be seen usually until many years later.
As an example, a research summary of non-linear receivers for Unique Word OFDM (orthogonal frequency division multiplexing) is presented, where several data detection techniques for MIMO (multi-antenna) communication systems are reused for a single-antenna setup. This is enabled by the UW-OFDM concept, which opens the range from Bayesian linear data estimation to maximum likelihood detection, opposing to the formerly dull data detection method for classical OFDM.
As an industry example, the limiting factors of the signal sensitivity in FMCW (frequency modulated continuous wave) Radar transceivers are addressed. The problem of on-chip leakage is an inherent problem of signal processing in MMICs (monolithic microwave integrated circuits). How it has been handled in communication ICs might be a clue for how to remarkably enhance FMCW Radar in the future.
Alexander Onic is currently Concept Engineer for automotive Radar at Infineon Technologies in Linz, Austria. He received the doctoral degree from Alpen-Adria-Universität Klagenfurt in 2013, where he was part of the research team that invented Unique Word OFDM, a novel signaling scheme for digital communication. In 2007, he graduated with the Dipl.-Ing. degree from Friedrich-Alexander-Universität Erlangen-Nürnberg, after studying electrical engineering with an emphasis on information technology and signal processing. Alex‘ research interest in signal processing, communication engineering and estimation theory is consequently supplemented by the research cooperation of Infineon and Johannes-Kepler-Universität Linz on Radar signal processing topics.
