摘要

本文讨论了用QPSK调制副载波强度的效果。在BPSK、OOK和PSK中，选择QPSK作为最佳调制方案。本文模拟了PSK-SIM、BPSK-SIM和QPSK-SIM在频谱效率(SE)为4bps/HZ的FSO系统中的应用，并在弱湍流和强湍流条件下进行了分析。研究表明，在不同湍流条件下，QPSK-SIM-FSO系统的误码率比PSK和BPSK-SIM-FSO系统高10−8as。

QPSK-Subcarrier Intensity modulated FSO System

The effect of Subcarrier intensity modulation with QPSK is discussed in this paper. QPSK is chosen as the best modulation scheme among BPSK, OOK and PSK. This work simulates PSK-SIM, BPSK-SIM and QPSK-SIM applied to FSO system at spectral efficiency (SE) of 4bps/HZ and the analysis is performed in weak and strong turbulence conditions. The investigation shows that QPSK-SIM-FSO system shows BER of the order of 10−8as compared to PSK and BPSK-SIM-FSO system in different turbulence conditions.
