Compressed Channel Sensing: A New Approach to Estimating Sparse Multipath Channels
TLDR
We formalize the notion of multipath sparsity and present a new approach to estimating sparse (or effectively sparse) multipath channels that is based on some of the recent advances in the theory of compressed sensing. Expand

  • 1 December 2013
TLDR
In this paper we propose and analyze the sum capacity of several linear, reduced-complexity multiuser MIMO (MU-MIMO) precoders that exploit the concept of beamspace MIMo (B-M IMO) communication - multiplexing data onto orthogonal spatial beams that serve as approximate channel eigenfunctions.

Joint multipath-Doppler diversity in mobile wireless communications
TLDR
We introduce a new approach for achieving diversity in spread-spectrum communications over fast-fading multipath channels and propose a framework that exploits joint multipath-Doppler diversity in an optimal fashion. Expand

Joint Source–Channel Communication for Distributed Estimation in Sensor Networks
TLDR
A distributed joint source-channel communication architecture for energy-efficient estimation of sensor field data at a distant destination and the corresponding relationships between power, distortion, and latency are analyzed as a function of number of sensor nodes. Expand
