Abstract :
A novel spread spectrum communication system is proposed, being characterized by a very compact yet efficient implementation. A particular elementary cellular automaton with rule 45 is used as the generator of spreading sequences while it also has synchronization capabilities. Simulations demonstrate that generated sequences are orthogonal and the performances of the proposed system are comparable to those of more sophisticated CDMA systems.
