It has been shown in [12] that quantized selected Super Stable Orbits (SSO) of the logistic map allow better performance in terms of the Average Interference Parameter (AIP) criterion than those allowed by Gold Sequences, when a conventional or decorrelator receiver is considered in a DS-CDMA system. In this paper we analyse the performance of the MMSE receiver when these orbits are considered. The motivation is that the performance of the MMSE receiver in term of error rate depends on the AIP. We find that the performance of the MMSE can be improved by considering non classical spreading sequences.
