Type-Based Decentralized Detection in Wireless Sensor Networks
Ke Liu,Akbar M. Sayeed +1 more
TL;DR: It is shown that uncoded histogram fusion over the MAC is also asymptotically optimal under sublinear network power scaling with an additional advantage: knowledge of observation statistics is needed only at the decision center.
Journal ArticleDOI
Orthogonal time-frequency signaling over doubly dispersive channels
Ke Liu,T. Kadous,Akbar M. Sayeed +2 more
TL;DR: The starting point of this work is a pulse scale adaptation rule first proposed by Kozek to minimize the interference between the basis functions, and the results indicate that the proposed STF signaling framework is applicable for spread factors as large as 0.01.
Journal ArticleDOI
Spatial multiplexing in correlated fading via the virtual channel representation
TL;DR: This paper studies the design and performance of spatial multiplexing techniques based on a virtual representation of realistic MIMO fading channels and proposes nonunitary precoding techniques to exploit channel structure when channel statistics are known at the transmitter.
Journal ArticleDOI
Capacity scaling and spectral efficiency in wide-band correlated MIMO channels
TL;DR: A D-connected model for correlated channels defined by a virtual spatial channel matrix consisting of D nonvanishing diagonals with independent and identically distributed (i.i.d.) Gaussian entries is proposed, which provides a meaningful and tractable measure of the richness of scattering.

The Three Node Wireless Network: Achievable Rates and Cooperation Strategies
TL;DR: A greedy cooperation framework applicable to both the multicast and three-way channels is identified and the asymptotic optimality of the proposed greedy approach and the central role of list source-channel decoding in exploiting the receiver side information in the wireless network setting is revealed.
