Abstract

In this paper we consider a wide band multiuser impulse modulation based system combined with DS-CDMA. We focus on the synchronization problem and we derive an optimal maximum likelihood metric for multiuser synchronization assuming an unstationary Gaussian noise model. Then, with the appropriate simplifications we obtain a simple implementation that is capable of achieving near optimal performance. The results show that the scheme allows for robust transmission over highly dispersive PL channels in the presence of impulse noise and multiple access interference.
