Research on Construction Method of Polarization Code in Wireless Optical Communication
To solve the problem of high complexity in the construction of polarization codes in wireless optical communication, a turbulence partial-order construction method with lower coding complexity is proposed, which is suitable for atmospheric weak turbulence channels. In this study, the conventional partial-order technique is introduced into the atmospheric weak turbulence channel, and the relationship among the subchannels of the weak turbulence is determined via Monte-Carlo method simulation. Combining the established relationship with the polarization weight formula, the optimal parameter value is derived. The simulation results show that under different intensities of atmospheric turbulence, the turbulence partial-order method can achieve the same bit error performance as the Monte-Carlo method at low bit rates, and its performance is also similar to that of the Monte-Carlo method at high bit rates, only 0.07-0.2 dB loss is generated at the bit error rate of 10 -4. This is suitable for the improvement of the transmission efficiency of the system and provides a solution for the efficient combination of polarization codes and wireless optical communication.
