时间：2018/11/8 周四上午 10：00-11：00
Abstract： Recently, Cassuto and Blaum introduced codes for symbol-pair read channels and Yaakobi et al. generalized the coding framework to that for b-symbol read channels where b≥2. In this talk, a b-sphere-packing bound will be established. Codes meeting this bound are called perfect b-symbol codes. We study the existence of linear perfect b-symbol e-error-correcting codes over finite fields for e<3b. In particular, we construct a family of linear perfect b-symbol b-error-correcting codes by using constacyclic codes.
