Welcome to the Institute of Digital Signal Processing!


Localization becomes more and more relevant for our society. For instance, the Global Positioning System (GPS) is meanwhile almost seaminglessly integrated in our daily live - navigation devices inside vehicles and nowadays navigation via smartphones are two prominent examples. In general, the objective of localization is - more or less- to accurately determine someone’s and/or something’s position in a geographical region by means of wireless signal transmission and complementary signal processing. Several centuries ago, explorers have used sextant and celestial map; today we use GPS for outdoor navigation, but which technology enables sufficiently accurate indoor navigation? How to let a robot automatically explore buildings? How to easily find my laptop, my cell phone, my pet? All these questions are technically not well solved yet and DSV scientists are contributing to them since more than five years. Numerous results have been published, including new localization algorithms, e.g. by exploiting antenna characteristics and path-loss information, the maximum achievable localization accuracy by deriving Cramer-Rao lower bounds, the identification of Non-Line-of-Sight scenarios and undesired path mitigation, the BeamLoc approach for boosting the direct path signal between transmitter and receiver, several UWB-based localization schemes for improving indoor accuracy, etc..

Nowadays, DSV concentrates on indoor localization algorithms for standardized wireless communication systems such as IEEE 802.11..., 3GPP LTE, , RFID and also for wireless systems with extreme bandwidth.

According to DSV’s motto Think complete. a suitable platform is currently under construction with the aim of demonstrating location capabilities being integrated into leading wireless communication standards.
