Code Division Based on M-sequences and Its Optimization

Dmitry Kukunin, Aleksandr Berezkin, Ruslan Kirichek
The work contains a description of methods for creating orthogonal constructions based on recurrent sequences of maximum length. These structures are formed when the signal spectrum is spread by direct sequences and provide signal densification, as well as code division of channels. At the same time, an effective way of optimizing orthogonal structures is proposed, which should increase the energy efficiency of the signal.
