This paper presents a theoretical model of a reverse CDMA link that uses noise-like spreading sequences in the case when AWGN and flat fading are present in the channel. It is known fact that the fading can be mitigated by the use of a block interleaver/deinterleaver structure. However, how to mitigate fading in a CDMA link that uses noise-like spreading(More)
A mathematical model and a simulator for a reverse link of a direct sequence code division multiple access (DS-CDMA) system are developed under the assumption that the spreading signals are binary chaotic sequences which are generated by using a logistic map. The system is analyzed for two channels: the additive white Gaussian noise (AWGN) channel and the(More)
