Abstract
A seed generator for a scrambler comprises a seed set identifier that identifies a seed set based on received user data symbols, which include a plurality of M-bit symbols. A seed selector selects a scrambling seed for the scrambler from the seed set based on Hamming distances between at least two of the M-bit symbols in the seed set.
