Talk:Complementary sequences

From Wikipedia, the free encyclopedia

As much as I am aware Golay complementary sequences have no connection to Golay codes. Golay complementary sequences are pairs of sequences of lenghtt 2, 4, 8, 10, 16, 26, 32, ... with some special autocorrelation properties. Golay codes are perfect error correting codes of length 23. The only thing they have in common is the name of the autor.

So I propose to remove the section "See also" containing Golay codes and related links. This is similar to putting links to the Complementary DNA sequences in the "See also" section just because the word complementary appears in both terms.

I propose to put a link to "Maximum length sequences" (or m-sequences or PN-sequences) instead. I intend to do that after writing a section comparing Golay complementary sequences to PN sequences.

The "see also" section of an article serves to list other topics that a reader might reasonably be interested in. Insofar as they are named after Golay, and concern sequences of binary digits, they seem related enough to be included in a see-also section. Adding complementary DNA sequences to the see-also list would be entirely appropriate, precisely because the phrase "complimentary sequence" appears in both of them. By contrast, phrases that appear directly in the article should not be placed in the see-also section. Thus, it would be wrong to put "maximum length sequence" in the see-also section. linas 03:49, 22 February 2007 (UTC)

I agree with you about "maximum length sequences". If I understand correctly it would be appropriate to put them now in the see-also section because they are not mentioned in the article. Later when I (or somebody else) write the section comparing CS to PN sequences I will remove them from the see-also. I can also agree that Golay sequences have in common that they are sequences (codess) of binary digits. But what about reference to Mathieu group, Steiner system, Leech lattice? They are all related only to Golay codes and not to Golay complementary sequences. Wouldn't it be more appropriate to include links to some other binary sequences (Gold sequences, Kasami sequences)?
