On the Existence of Perfect Codes for Asymmetric Limited-Magnitude Errors (1112.0896v2)
Published 5 Dec 2011 in cs.IT and math.IT
Abstract: Block codes, which correct asymmetric errors with limited-magnitude, are studied. These codes have been applied recently for error correction in flash memories. The codes will be represented by lattices and the constructions will be based on a generalization of Sidon sequences. In particular we will consider perfect codes for these type of errors.
