Research on Polarization Coding Cooperative Communication Scheme for FSO System

To solve the problems of interruption events and high bit-error rate FSO system caused by atmospheric turbulence, an cooperative communication scheme based on polarization code is proposed. In this scheme, upper limit average turbulence channel used to construct frozen bit set code, information S−R link recovered using ownership relationship between S−D at destination node. Finally, bits are combined equal gain combination, original decoding. The simulation results show that can overcome influence improve performance, performance be improved least 0.5dB; outage probability reduced less than 10−7, it shows a stable inhibitory effect strong conditions.
