Study of vehicle noise for different operating conditions

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

The noise emission level from a vehicle is significantly influenced by different driving conditions and drivers’ behaviour. Almost all the in practice road traffic noise estimation models do not differentiate between different operating conditions. In this ...

SURE-Based Wavelet Thresholding Integrating Inter-Scale Dependencies

Michaël Unser, Thierry Blu, Florian Luisier

We propose here a new pointwise wavelet thresholding function that incorporates inter-scale dependencies. This non-linear function depends on a set of four linear parameters per subband which are set by minimizing Stein's unbiased MSE estimate (SURE). Our ...

Network-based wireless location: challenges faced in developing techniques for accurate wireless location information

Ali H. Sayed

Wireless location refers to the geographic coordinates of a mobile subscriber in cellular or wireless local area network (WLAN) environments. Wireless location finding has emerged as an essential public safety feature of cellular systems in response to an ...

A Distributed Broadcasting Time-Synchronization Scheme for Wireless Sensor Networks

Ali H. Sayed

This paper proposes a globally distributed synchronization algorithm for wireless sensor networks. In the proposed scheme, there is a master node that controls the network synchronization and the other sensors periodically broadcast synchronization pulses; ...

RAYLEIGH FADING MULTIPLE ACCESS CHANNEL WITHOUT CHANNEL STATE INFORMATION

Ninoslav Marina

In this paper we determine bounds of the capacity region of a two-user multiple-access channel with Rayleigh fading when neither the transmitters nor the receiver has channel state information (CSI). We assume that the fading coefficients as well as the ad ...

Successive decoding

Ninoslav Marina

As the demand for wireless mobile communication services is constantly growing, the need for mobile systems and devices that support much higher data rates is increasing. The available bandwidth is limited and expensive, thus we need new technologies that ...

Robust wireless location over fading channels

Ali H. Sayed

This paper develops an estimation algorithm for the time and amplitude of arrival of a known transmitted sequence over a single-path fading channel. The algorithm is optimized to enhance robustness to fast channel fading and low signal-to-noise ratio (SNR) ...

Fundamentals of adaptive filtering

Ali H. Sayed

This graduate-level textbook offers a comprehensive and up-to-date treatment of adaptive filtering; a vast and fast-moving field. The book is logically organized, specific in its presentation of each topic, and far-reaching in scope. Throughout the present ...

Adaptive Multipath resolving for wireless location systems

Ali H. Sayed

We develop an adaptive technique for resolving overlapping multipath components. The technique relies on replacing the least-squares operation needed for resolving overlapping components by a gradient-based adaptive filter with projections. The projections ...
