Comparison of Three Schemes for Intermediate Data Rate Frame Synchronization

Zhanhe Wang, Mao-Teng Xing, Hua Wang, Jingming Kuang

Abstract

Based on the frame structure of intermediate data rate (IDR) modem for satellite communication, a new method for searching frame synchronization called group frame synchronization is proposed. At the same time, a candidate scheme in the classical frame synchronization and two candidate schemes in the group frame synchronization are presented, and the circuits for each scheme are designed in order to abstract the frame alignment signals from received data. Their implementation complexity and performances are also computed and given. Based on the analysis and performance comparison, a reasonable scheme is chosen and then verified through software simulation and hardware impletentation.
