Noncoherent digital delay lock loops (DDLL) are suited for chip timing synchronisation in band-limited direct-sequence spread-spectrum (DSSS) demodulators. The diffusion approximation and the singular perturbation method are used in this paper to calculate the mean time to lose lock (MTLL) of the DD

## Abstract In this Letter the effect of using pulse conformation techniques over a DSSS wireless optical system is explored. The performances of both Gaussian and sinusoidal conformation over the spread and code signal are compared. As a pattern of comparison, the side‐lobe elimination for adjacen
