Density of Spherically-Embedded Stiefel and Grassmann Codes
Renaud-Alexandre Pitaval, Lu Wei, Olav Tirkkonen +1
The density of a code is the fraction of the coding space covered by packing balls centered around the codewords. This paper investigates the density of codes in the complex Stiefe…
Volume of Metric Balls in High-Dimensional Complex Grassmann Manifolds
Renaud-Alexandre Pitaval, Lu Wei, Olav Tirkkonen +1
Volume of metric balls relates to rate-distortion theory and packing bounds on codes. In this paper, the volume of balls in complex Grassmann manifolds is evaluated for an arbitrar…
Asymptotic Matrix Variate von-Mises Fisher and Bingham Distributions with Applications
Lu Wei, Jukka Corander
Probability distributions in Stiefel manifold such as the von-Mises Fisher and Bingham distributions find diverse applications in signal processing and other applied sciences. Use…
From Random Matrix Theory to Coding Theory: Volume of a Metric Ball in Unitary Group
Lu Wei, Renaud-Alexandre Pitaval, Jukka Corander +1
Volume estimates of metric balls in manifolds find diverse applications in information and coding theory. In this paper, some new results for the volume of a metric ball in unitary…
Outage Capacity of Rayleigh Product Channels: a Free Probability Approach
Zhong Zheng, Lu Wei, Roland Speicher +3
The Rayleigh product channel model is useful in capturing the performance degradation due to rank deficiency of MIMO channels. In this paper, such a performance degradation is inve…
On the Outage Capacity of Orthogonal Space-time Block Codes Over Multi-cluster Scattering MIMO Channels
Lu Wei, Zhong Zheng, Jukka Corander +1
Multiple cluster scattering MIMO channel is a useful model for pico-cellular MIMO networks. In this paper, orthogonal space-time block coded transmission over such a channel is con…
