BER Performance Analysis of MIMO-CPolSK Using on Free-Space Optical Communications

Abstract:

Enslaved by atmospheric turbulence and transmission power, performance of Free-space Optical Communication (FSO) fluctuates greatly. A new communication system of MIMO-CPolSK combined the MIMO system and CPolSK modulation is proposed in this paper. According to the strength of turbulence, different mathematical models of atmospheric channel are adopted. The BER calculating formula of SISO-CPolSK is proposed at first, then the BER performance of MISO-CPolSK and MIMO-CPolSK system is presented. The result of numerical simulation shows that BER performance is greatly promoted in MIMO system and compared to OOK modulation, the SNR of receiving in CPolSK modulation is reduced about 3dB when the system has the same BER performance under the same condition.
