Optimum and Adaptive Complex-Valued Bilinear Filters
Bernhard Plaimer, Matthias Wagner, Oliver Lang +1
The paper extends real-valued bilinear adaptive filters to the complex domain and proposes several new complex-valued bilinear filters, evaluating their computational cost and perf…
On the CRLB for Blind Receiver I/Q Imbalance Estimation in OFDM Systems: Efficient Computation and Closed-Form Bounds
Moritz Tockner, Oliver Lang, Andreas Meingassner-Lang +1
Modern mobile communication receivers are often implemented with a direct-conversion architecture, which features a number of advantages over competing designs. A notable limitatio…
Detection of weak signals under arbitrary noise distributions
J. Zschetzsche, M. Weimar, O. Lang +7
Detecting weak signals buried in complex, non-Gaussian noise is a fundamental challenge in science and engineering, with applications ranging from radar systems and communications…
Bi-Linear Homogeneity Enforced Calibration for Pipelined ADCs
Matthias Wagner, Oliver Lang, Esmaeil Kavousi Ghafi +3
Pipelined analog-to-digital converters (ADCs) are key enablers in many state-of-the-art signal processing systems with high sampling rates. In addition to high sampling rates, such…
Automotive Radar Online Channel Imbalance Estimation via NLMS
Esmaeil Kavousi Ghafi, Oliver Lang, Matthias Wagner +2
Automotive radars are one of the essential enablers of advanced driver assistance systems (ADASs). Continuous monitoring of the functional safety and reliability of automotive rada…
Estimators and Performance Bounds for Short Periodic Pulses
Sebastian Schertler, Oliver Lang, Jonas Lindenberger +5
In many industrial applications, signals with short periodic pulses, caused by repeated steps in the manufacturing process, are present, and their fundamental frequency or period m…
