| description | To solve the problems of interruption events and the high bit-error rate of the FSO system caused by atmospheric turbulence, an FSO cooperative communication scheme based on system polarization code is proposed. In this scheme, the upper limit of the average bit-error rate of the atmospheric turbulence channel is used to construct the frozen bit set of the system polarization code, and the information bit set of the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>S</mi><mo>−</mo><mi>R</mi></mrow></semantics></math></inline-formula> link is recovered by using the ownership relationship between the frozen bit set of the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>S</mi><mo>−</mo><mi>R</mi></mrow></semantics></math></inline-formula> link and the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>S</mi><mo>−</mo><mi>D</mi></mrow></semantics></math></inline-formula> link at the destination node.

The simulation results show that the FSO cooperative communication system can overcome the influence of atmospheric turbulence and improve the system performance, and the bit-error rate performance of the FSO cooperative communication system can be improved by at least 0.5dB; the outage probability of the FSO cooperative communication system can be reduced to less than 10<sup>−7</sup>, and it shows a stable inhibitory effect on strong turbulence conditions. |
