A fast synchronous acquisition method which is applied to Direct Optical Switching-Code Division Multiple Access (DOS-CDMA) scheme in Software Definable Radio Networks (SDRNs) is proposed. This paper shows that the chaotic synchronization enables to reduce synchronous acquisition time in DOS-CDMA scheme compared to the sliding correlation method.
In case that code length is 121, reduction effect of synchronous acquisition time of 95% is obtained by the computer simulations.
