A Linear State Space Model for Photoacoustic Imaging in an Acoustic Attenuating Media
Oliver Lang, Peter Kovacs, Christian Motz +3
In photoacoustic imaging, ultrasound waves generated by a temperature rise after illumination of light absorbing structures are measured on the sample surface. These measurements a…
A Robust Nonlinear RLS Type Adaptive Filter for Second-Order-Intermodulation Distortion Cancellation in FDD LTE and 5G Direct Conversion Transceivers
Andreas Gebhard, Oliver Lang, Michael Lunglmayr +7
Transceivers operating in frequency division duplex experience a transmitter leakage (TxL) signal into the receiver due to the limited duplexer stop-band isolation. This TxL signal…
Knowledge-Aided Kaczmarz and LMS Algorithms
Michael Lunglmayr, Oliver Lang, Mario Huemer
The least mean squares (LMS) filter is often derived via the Wiener filter solution. For a system identification scenario, such a derivation makes it hard to incorporate prior info…
Constrained Best Linear Unbiased Estimation
Oliver Lang, Mario Huemer, Markus Steindl
The least squares (LS) estimator and the best linear unbiased estimator (BLUE) are two well-studied approaches for the estimation of a deterministic but unknown parameter vector. I…
