摘要：
A linear code with a complementary-dual (an LCD code) is defined to be a linear code C satisfying C boolean AND C-perpendicular to = {0}. We provide a necessary condition for an LCD linear code C over a finite chain ring. Under suitable conditions, we give a sufficient condition under which a linear code C over a finite chain ring is LCD. In particular, we derive a necessary and sufficient condition for free linear codes over a finite chain ring to be LCD. We also give a characterization of LCD codes over principal ideal rings.
