Analysis of quantitative differences in large-aperture size for free-space optical communication systems with circle polarization shift keying and on-off keying in atmospheric turbulence channels
Proceedings of SPIE - The International Society for Optical Engineering(2010)
摘要
A theoretical model is proposed to study quantitative differences in the size of large-aperture between circle polarization shift keying (CPolSK) and on-off keying (OOK). The quantitative differences can be analyzed with the impact from atmospheric condition, link length, and communication wavelength. Numerical results show that FSO CPolSK systems with longer communication wavelength can reduce the size even smaller than the systems using OOK, while it can be not obvious with increasing link length. Meanwhile, increasing average signal-to-noise ratio (SNR) leads to a reduction of the difference in aperture size. These results can be helpful for FSO systems design. © 2010 Copyright SPIE - The International Society for Optical Engineering.
