CMA and Soft Decision-Directed Scheme for Semi-Blind Beamforming of QAM Systems
— We propose a semi-blind adaptive beamforming approach for wireless systems that employ high-throughput quadrature amplitude modulation signalling schemes. A minimum number of t...

Heuristic Motion Planning with Many Degrees of Freedom
We present a heuristic approach to the geometric motion planning problem with the aim to quickly solve intuitively simple problems. It is based on a divide-and-conquer path search...

Particle filtering based recovery of noisy GARCH processes
In this paper, we address the problem of enhancement of a noisy GARCH process using a particle filter. We compare our approach experimentally to a previously developed recursive ...
