摘要

涡轮代码可以关闭到香农限制，并有望用于可靠的应用程序。采用混合BPPM-OOK的光-无线turbo编码系统在误码率性能上优于其他脉冲调制方案。实现混合BPPM-OOK光-无线turbo编码系统需要实现帧同步方案。提出了混合BPPM-OOK turbo编码系统的帧同步方案。该方案着重于框架结构，该框架结构由两个BPPM槽和两个OOK槽组成。计算了帧定时信号的检测概率和平均虚警概率。然而，赛车计数器上的赛段数很难优化。本文通过对保持时间和恢复时间的评估，推导出帧同步系统中竞速计数器各阶段的优化问题。结果发现，根据所需的恢复时间，赛车计数器上的最佳阶段数是不同的。

Frame Synchronization Performance of Optical-Wireless Hybrid BPPM-OOK System

Turbo code can be closed to the Shanon limit and is expected to be used for reliable applications. The optical-wireless turbo coded system with a hybrid BPPM-OOK is superior to those using other pulse modulation schemes in bit error rate performance. To realize the optical-wireless turbo coded system with hybrid BPPM-OOK demands the implementation of frame synchronization schemes. The frame synchronization scheme for the turbo coded system with hybrid BPPM-OOK are proposed. The scheme is focused on the frame structure which consists of two slots for BPPM and two slots for OOK. The detection probability of frame timing signal and the average false alarm probability are evaluated. However, it is difficult to optimize the number of stages on the racing counters. In this paper, the retention time and the recovery time are evaluated to derive the optimization of the stages of racing counters in the frame synchronization system. As a result, it is found that the optimum number of stages on racing counters varies according to required recovery time.
