N2 - The cross-correlation function and the side-lobes of the auto-correlation function of LS codes are zero in a certain vicinity of the zero shift. Therefore, the effects of the Inter-Symbol-Interference and Multiple-Access- Interference that appears in CDMA and multi-sensor systems are mitigated. Conventionally, the detection of these sequences has been achieved by means of straight-forward matched-filter correlators. In this paper, a new correlator which significantly reduces the total number of operations to be performed is proposed, allowing real-time operation.
