Abstract:

Atmospheric optical wireless channel is a time-varying optical channel because of the effect of scintillation, the paper introduces rate compatible punctured turbo code (RCPTC) scheme to provide unequal error protection (UEP) for optical wireless communication. In order to use RCPTC over optical wireless channel, the paper firstly proposed a turbo decoder with iterative optical channel estimation for optical wireless channel. Simulations show that the proposed turbo decoder significantly improves the performance of the system. Based on the proposed turbo decoder, the paper compares several RCPTC schemes via simulations. In these RCPTC schemes, the non-uniformly punctured code schemes are compared with uniformly punctured code scheme. Moreover, the systematic and non-systematic puncturing schemes are both discussed.
