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 "constructions of fast decodable distributed space time codes"):
  Abstract: Fast-decodable distributed space-time codes are constructed by adapting the iterative code construction introduced in [1] to the N -relay multiple-input multiple-output channel, leading to the first fast-decodable distributed space-time codes for more than one antenna per user. Explicit constructions are provided alongside with a performance comparison to non-iterated (non-) fast-decodable codes.

Includes members:
  Member "fast decodable asymmetric space time codes from division algebras":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "a survey on mimo transmission with discrete input signals technical challenges advances and future trends")
  Member "iterated space time code constructions from cyclic algebras":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a survey on mimo transmission with discrete input signals technical challenges advances and future trends")
  Member "algebraic fast decodable relay codes for distributed communications":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "fast decodable space time codes for the n relay and multiple access mimo channel")
  Member "on fast decodable space time block codes":
    also connected through other hyperedges:
      - Hyperedge HE-4 (induced by source paper "a survey on mimo transmission with discrete input signals technical challenges advances and future trends")
  Member "optimal space time codes for the mimo amplify and forward cooperative channel":
    also connected through other hyperedges:
      - Hyperedge HE-5 (induced by source paper "unmanned aerial vehicle assisted cellular communication")
