human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "the nonassociative algebras used to build fast decodable space time block codes"):
  Abstract: Let $K/F$ and $K/L$ be two  cyclic Galois field extensions  and $D=(K/F,\sigma,c)$ a cyclic algebra. Given an#R##N#invertible element $d\in D$,#R##N#we present three families of unital nonassociative algebras over $L\cap F$ defined#R##N#on the direct sum of $n$ copies of#R##N# $D$.#R##N#Two of these families appear either explicitly or implicitly in the designs of fast-decodable space-time block codes#R##N#in  papers#R##N#by Srinath, Rajan, Markin, Oggier, and the authors.#R##N#We present conditions for the algebras to be division and propose a construction for fully diverse#R##N# fast decodable space-time block codes of rate-$m$ for $nm$ transmit and $m$ receive antennas.#R##N#We present a  DMT-optimal rate-3 code for 6 transmit and 3 receive antennas which is fast-decodable,#R##N#with ML-decoding complexity#R##N#at most $\mathcal{O}(M^{15})$.
