I want to cross correlate two binary signals, where one is currupted by noise and shifted by a timeconstant tau, but has the same bit pattern (so basically an auto correlation). Similiar to case 2 in this article: https://www.allaboutcircuits.com/technical-articles/understanding-correlation/

My question is, how long my bit pattern must be, so that i have a large error safety?

Any advice on literature, Research papers or links are greatly appreciated!
