Robust synchronization for asynchronous Multi-User chaos-based DS-CDMA

摘要: In this paper we propose two systems for achieving synchronization in asynchronous multi-user chaos-based DS-CDMA. For the first system, process is realized thanks to a binary code used as an additive pilot sequence spreaded signal. Gold sequences are signals different users accomplish synchronization. second made through multiplicative signal data sequence. These processes evaluated under assumption of white Gaussian noise channel together with interferences. will focus on initial phase (code acquisition) and assume that system can achieve correctly tracking after phase. The acquisition terms probability detection false alarm.
