MacWilliams identity for -spotty Lee weight enumerators

It is a well established fact that m -spotty byte error control codes provide a good source for detecting and correcting errors in semiconductor memory systems using high-density RAM chips with wide I/O data (e.g. 8, 16 or 32 bits). Recently, a MacWilliams identity that establishes an important relation between an m -spotty weight enumerator of a binary code and its dual has been proven in Kazuyoshi Suzuki et al. (2007) [5]. In this paper, we introduce the m -spotty Lee weights and the m -spotty Lee weight enumerator of a quaternary code and prove a MacWilliams type identity.
