Signal recovery algorithms utilizing bispectral slices were implemented to extract CDMA (code division multiple access) signals from residual noise. It is assumed that any jamming or undesirable interference has been mitigated using signal separation techniques or space time processing algorithms prior to using bispectral slices. This paper proposes a methodology for removing remaining residual contamination using bispectral-based signal recovery techniques. More specifically, this paper uses phase recovery algorithms to recover a binary CDMA sequence embedded in noise. We compare three signal recovery algorithms and we discuss the utility of these techniques in CDMA communication.
