V-BLAST: an architecture for realizing very high data rates over the rich-scattering wireless channel
TL;DR: This paper describes a wireless communication architecture known as vertical BLAST (Bell Laboratories Layered Space-Time) or V-BLAST, which has been implemented in real-time in the laboratory and demonstrated spectral efficiencies of 20-40 bps/Hz in an indoor propagation environment at realistic SNRs and error rates.
Journal ArticleDOI
A Statistical Model for Indoor Multipath Propagation
TL;DR: The results of indoor multipath propagation measurements using 10 ns, 1.5 GHz, radarlike pulses are presented for a medium-size office building, and a simple statistical multipath model of the indoor radio channel appears to be extendable to other buildings.
Journal ArticleDOI
Detection algorithm and initial laboratory results using V-BLAST space-time communication architecture
TL;DR: Using this joint space-time approach, spectral efficiencies ranging from 20-40 bit/s/Hz have been demonstrated in the laboratory under flat fading conditions at indoor fading rates.
Proceedings ArticleDOI
MIMO radar: an idea whose time has come
E. Fishler,Alexander M. Haimovich,Rick S. Blum,Dmitry Chizhik,Leonard J. Cimini,Reinaldo A. Valenzuela +5 more
TL;DR: It is shown that MIMO radar leads to significant performance improvement in DF accuracy, and is carried out in terms of the Cramer-Rao bound of the mean-square error in estimating the target direction.

Spatial Diversity in Radars—Models and Detection Performance
E. Fishler,Alexander M. Haimovich,Rick S. Blum,Leonard J. Cimini,Dmitry Chizhik,Reinaldo A. Valenzuela +5 more
TL;DR: The optimal detector in the Neyman–Pearson sense is developed and analyzed for the statistical MIMO radar and it is shown that the optimal detector consists of noncoherent processing of the receiver sensors' outputs and that for cases of practical interest, detection performance is superior to that obtained through coherent processing.
