The separability of standard cyclic N-ary Gray codes
A.J. van Zanten, I Nengah Suparta · IEEE Transactions on Information Theory · 2003
A sharp lower bound is derived for the cyclic list distance between two codewords, having Hamming distance m, in the standard N-ary Gray code of length n, for 1/spl les/m/spl les/n and for even values of N. The bound generalizes a similar result in the binary case.
