Unequal dimensional small balls and quantization on Grassmann Manifolds
Wei Dai, Brian Rider, Youjian Liu
The Grassmann manifold G_{n,p}(L) is the set of all p-dimensional planes (through the origin) in the n-dimensional Euclidean space L^{n}, where L is either R or C. This paper consi…

Quantization Bounds on Grassmann Manifolds of Arbitrary Dimensions and MIMO Communications with Feedback
Wei Dai, Youjian Liu, Brian Rider
This paper considers the quantization problem on the Grassmann manifold with dimension n and p. The unique contribution is the derivation of a closed-form formula for the volume of…

Multi-Access MIMO Systems with Finite Rate Channel State Feedback
Wei Dai, Brian Rider, Youjian Liu
This paper characterizes the effect of finite rate channel state feedback on the sum rate of a multi-access multiple-input multiple-output (MIMO) system. We propose to control the…
