Chaotic sequences for multiple access

D. Sandoval-Morantes, David Munoz

Abstract

The use of chaotic signals as generators of binary and multilevel sequences suitable for code division multiple access (CDMA) is proposed. The number of obtained sequences is found to be greater than the number of m-sequences of the same length. These new chaotic sequences are used as spreading codes in a CDMA system. Simulation results are presented and compared with those obtained for m-sequences in terms of BER performance.
