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 "decoding q ary lattices in the lee metric"):
  Abstract: q-ary lattices can be obtained from q-ary codes using the so-called Construction A. We investigate these lattices in the Lee metric and show how their decoding process can be related to the associated codes. For prime q we derive a Lee sphere decoding algorithm for q-ary lattices, present a brief discussion on its complexity and some comparisons with the classic sphere decoding.

Includes members:
  Member "dense error correcting codes in the lee metric":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "on the linear programming bound for lee codes")
  Member "error correction of multidimensional bursts":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "the set of dimensions for which there are no linear perfect 2 error correcting lee codes has positive density")
  Member "mutual information and minimum mean square error in gaussian channels":
    also connected through other hyperedges:
      - Hyperedge HE-3 (induced by source paper "on the information bottleneck problems models connections applications and information theoretic views")
