Journal ArticleDOI
Channel capacity of MIMO architecture using the exponential correlation matrix
TL;DR: This letter investigates the MIMO channel capacity in correlated channels using the exponential correlation matrix model and proves that, for this model, an increase in correlation is equivalent to a decrease in signal-to-noise ratio (SNR).
Journal ArticleDOI
Performance analysis of the V-BLAST algorithm: an analytical approach
Sergey Loyka,Francois Gagnon +1 more
TL;DR: This approach presents a new geometrical view of the V-BLAST and explains some of its properties in a complete and rigorous form, including a statistical analysis of postprocessing signal-to-noise ratios for a 2/spl times/n system.
Journal ArticleDOI
Estimating MIMO system performance using the correlation matrix approach
Sergey Loyka,George V. Tsoulos +1 more
TL;DR: It is shown that for a linear array, correlation has no impact on the MIMO channel capacity provided that the two-element array beamwidth is smaller than the angle spread of the incoming signals.
Proceedings ArticleDOI
Performance analysis of the V-BLAST algorithm: an analytical approach
Sergey Loyka,Francois Gagnon +1 more
TL;DR: An analytical approach to the performance analysis of the V-BLAST (vertical Bell Labs layered space-time) algorithm is presented, based on the analytical model of the Gramm-Schmidt process, and it is shown that the optimal ordering isbased on the least correlation criterion.
Journal ArticleDOI
On the Outage Capacity Distribution of Correlated Keyhole MIMO Channels
G. Levin,Sergey Loyka +1 more
TL;DR: The fact that, despite the strong degenerate nature of the keyhole channel, its outage capacity distribution is asymptotically normal indicates that Gaussian distribution has a high degree of universality for the capacity analysis of MIMO channels.
