De Bruijn binary sequences and spread spectrum applications: A marriage possible?

The evaluations and results provided in the show that a proper selection of De Bruijn binary sequences as spreading codes in multiuser communications allows to obtain improved performance, with respect to more traditional solutions, like those based on the use of classical Gold codes, m sequences, and OVSF codes. Promising results have been obtained also in DS sequence SS radar simulations, where the number of available sequences may be important to cope with specific scenarios, such as anticollision vehicular radar applications. The behavior exhibited by De Bruijn sequences motivates the efforts aimed at providing an efficient generation algorithm to obtain the complete set of codes for even greater values of n and performing an exhaustive evaluation of their properties. This activity is currently ongoing.
