Fast-decodable MIDO codes from non-associative algebras (2015)
Journal Article
Pumpluen, S., & Steele, A. (2015). Fast-decodable MIDO codes from non-associative algebras. International Journal of Information and Coding Theory, 3(1), https://doi.org/10.1504/IJICOT.2015.068695

By defining a multiplication on a direct sum of n copies of a given cyclic division algebra, we obtain new unital non-associative algebras. We employ their left multiplication to construct rate-n and rate-2 fully diverse fast ML-decodable space-time... Read More about Fast-decodable MIDO codes from non-associative algebras.

A diffusion process associated with Fréchet means (2015)
Journal Article
Le, H. (2015). A diffusion process associated with Fréchet means. Annals of Applied Probability, 25(6), https://doi.org/10.1214/14-AAP1066

This paper studies rescaled images, under exp−1μ, of the sample Fréchet means of i.i.d. random variables {Xk|k≥1} with Fréchet mean μ on a Rie-mannian manifold. We show that, with appropriate scaling, these images converge weakly to a diffusion proce... Read More about A diffusion process associated with Fréchet means.
