摘要：
In this paper, we propose a novel code acquisition scheme called enhanced multiple-shift (EMS) for optical code division multiple access (CDMA) systems. By using multiple thresholds, the proposed EMS scheme provides a shorter mean acquisition time (MAT) than that of the conventional multiple-shift, (MS) scheme. The simulation results demonstrate that the MAT of EMS scheme is shorter than that of MS scheme ill both single-user and multi-user environments.
