The Polar Code Construction Method in Free Space Optical Communication

In order to solve the problem of high complexity polarization code construction under free-space optical communication, this paper proposes a segmented turbulent partial method, which effectively reduces while obtaining highest possible quality communication performance. The method introduces generalized technique into atmospheric strong channel, determines reliability relationship between each sub-channel in turbulence using Monte Carlo simulation, and combines it with weight formula find optimal parameter values different signal-to-noise ratio ranges construct code. simulation results showed that had similar performance compared conventional for intensities, rates, lengths, its was negligible due offline operation nature. For rate lengths BER 10-4, generated about 0.03–0.17 dB loss method; strengths only 0.05–0.07 generated. It provides solution efficient application codes communication.
