Abstract

With the correlation of truncated chaotic sequences

the correlated demodulation for asynchronous DS-CDMA system in chaotic sequence is derived in the paper.It is shown that the system has multiple access and is robust by the theoretical analysis and computer simulations.Finally an optimization method of the chaotic spreading sequences is proposed.
