Abstract:
We propose a performance model for a multi-format-compatible free-space optical communication system and establish an experimental platform supporting OOK, DPSK, QPSK, and PM-QPSK at format-dependent data rates up to 40 Gbps. The model-based simulations show overall agreement with the 12-km near-ground experiments in BER trends, relative performance, and operating ranges, supporting the validity of the model. PM-QPSK supports high-rate transmission at SI = 0.0963 when sufficient received power is available, QPSK provides a favorable balance between transmission rate and reliability at SI = 0.2039, and DPSK requires the lowest received power at SI = 0.3527. These results provide guidance for modulation-format selection in turbulence-impaired FSO systems.
