A Fast Code Acquisition Scheme for O-CDMA Systems

This paper proposes a fast code acquisition scheme for optical code division multiple access (O-CDMA) systems. Unlike the conventional scheme, the proposed scheme employs multiple thresholds providing a shorter mean acquisition time (MAT) performance. The simulation results show that the MAT of the proposed scheme is shorter than that of the conventional scheme. Keywords—Optical CDMA, acquisition, MAT, multiple-shift
