Abstract

In order to solve the low efficiency problem of symbol synchronization in laser communication,a super-frame synchronization was proposed instead of symbol synchronization.On the basis of analyzing multi-pulse position moudulation (MPPM)code pattern and length,the different methods of combination Barker sequence applied in the super-frame synchronization of MPPM were analyzed, and the length of synchronization code of the different frame was calculated.The simulation results show that this method can decode the input binary bits accurately.The obtained results have theoretic reference value for the improving the performance of laser communication.
