I know nothing about the math used to develop them. An OLD memory says that the longest-known code is 17 chips, but the commenter says the longest-known is 13, and on reflection I think that's correct.

In the transmitter, the 11-bit Barker code is applied to a modulo-2 adder together with each of the information bits in the PPDU. The output of the modulo-2 adder results in a signal with a data rate that is 10 times higher than the information rate. phenix lumber
