Cooperative Location-Sensing for Wireless Networks
We present the Cooperative Location-sensing system (CLS), an adaptive location-sensing system that enables devices to estimate their position in a self-organizing manner without t...

MMSE based noise PSD tracking with low complexity
Most speech enhancement algorithms heavily depend on the noise power spectral density (PSD). Because this quantity is unknown in practice, estimation from the noisy data is necess...

Iterative SIC receiver scheme for non-orthogonally superimposed signals on top of OFDMA
In this paper, we propose an iterative SIC receiver architecture with pilot- and data-based channel estimation for efficient decoding of non-orthogonal superimposed signals. The no...

Measuring Transmission Opportunities in 802.11 Links
Abstract-- We propose a powerful MAC/PHY cross-layer approach to measuring 802.11 transmission opportunities in WLAN networks on a per-link basis. Our estimator can operate at a si...
