摘要
We study (1 + lambda p)-constacyclic codes over Z(pm) of an arbitrary length, where lambda is a unit of Z(pm) and m >= 2 is a positive integer. We first derive the structure of (1 + lambda p)-constacyclic codes of length p(s) over GR(p(m), a) and determine the Hamming and homogeneous distances of such constacyclic codes. These codes are then used to classify all (1 + lambda p)-constacyclic codes over Z(pm) of length N = p(s)n (n prime to p). In particular, the Gray images of (1 + lambda p)-constacyclic codes over Z(p2) are also discussed. (C) 2010 Elsevier Inc. All rights reserved.
