Design and Implementation of Signal Processing Systems

Short-Range Leakage Cancelation in FMCW Radar Transceivers


Our demonstrator verifies a novel concept to mitigate unwanted close signal reflections in FMCW radar transceivers. In automotive applications, for instance, these reflections originate from the car’s own bumper, causing a severe degradation of detection sensitivity and accuracy due to the unpreventable phase noise contained in the transmit signal. We propose a concept on how to mitigate the so-called Short-Range (SR) leakage in a recently puplished paper in the IEEE Journal of Selected Topics in Signal Processing (December 2015).

High-Accuracy Indoor Localization: A WiFi-based Approach


Indoor positioning systems (IPS) based on Wi-Fi signals are gaining popularity recently. IPS based on Received Signal Strength Indicator (RSSI) could only achieve a precision of several meters due to the strong temporal and spatial variation of indoor environment. On the other hand, IPS based on Channel State Information (CSI) drive the precision into the sub-meter regime with several access points (AP). However, the performance degrades with fewer APs mainly due to the limit of bandwidth.

Method for increasing reliability for signal transmission state of power equipment energy


information veracity

In this paper the problems of transmitting trustworthy monitoring and control signals through the communication channels of sophisticated telemechanics systems using the IEC 60870-5-101 (104) are debated (104). Mathematically justified discrepancy between concepts of "information veracity" and " information protection from noise in communication channel" is shown. Principles of combined encoding ensuring high level of veracity of systems intended for energy supply are proposed.
