Wavelet-domain compressive signal reconstruction using a Hidden Markov Tree model
Compressive sensing aims to recover a sparse or compressible signal from a small set of projections onto random vectors; conventional solutions involve linear programming or greed...

A Polynomial-Time Approximation Algorithm for Weighted Sum-Rate Maximization in UWB Networks
— Scheduling in an ad hoc wireless network suffers from the non-convexity of the cost function, caused by the interference between communication links. In previous optimization t...

Wireless Medium Access via Adaptive Backoff: Delay and Loss Minimization
— We consider packet transmission scheduling at the MAC-layer via adaptive backoff algorithms that are favorable in terms of queue occupancies in a wireless network. General netw...

Integrating Scan Design and Soft Error Correction in Low-Power Applications
— Error correcting coding is the dominant technique to achieve acceptable soft-error rates in memory arrays. In many modern circuits, the number of memory elements in the random ...
