摘要：
In this paper, a multicarrier direct sequence (DS) code division multiple access (CDMA) using chaotic spreading binary sequences having exponentially vanishing autocorrelations together with three classes of time-domain chip waveforms including rectangular, half-sine and raised-cosine chip waveforms is considered. The closed-form, equations allow us to evaluate the optimum autocorrelation parameters of spreading sequences associated with different chip waveforms in order to minimize bit error probability (BEP) of the multicarrier DS-CDMA with partially spectral overlapping subcarriers.
