Abstract：In this paper, a method of time synchronization of 2D Spread Spectrum (2DSS) system in multipath fading channels is proposed. The detection probability and false-alarm probability are analyzed and also the numerical results on condition of different normalized thresholds are presented. The theoretical results show that the mapped 2DSS system is equal to the 1D Spread Spectrum (1DSS) system. So the synchronization algorithm in the 1DSS system can be used in 2DSS system, and good synchronization performance can be obtained and its algorithm can be simplified.
