Abstract

Intensity density distribution which satisfies log-normal and Gamma-Gamma distribution together with pointing error distribution and channel attenuation are considered entirely when study the performance under circle polarization modulation system with coherent detection. The closed form expression of the bit error rate (BER) and outage probability were derived corresponding to Gamma-Gamma channel. In the different turbulence parameters, the performance of circle polarization communication system were simulated and analyzed. The results shows that the performance of BER are closed approximately in Gamma-Gamma and log-normal when the channel attenuation parameter is big enough . Furthermore, the less beginning threshold SNR was derived in the region of low SNR when weak turbulence compared to Strong turbulence. However, as the threshold SNR increasing, a stronger rising slope was showed in weak turbulence channel, which makes only 3dB gaps approximate when both of them arrive at complete outage.
