摘要
为了改善深空通信质量,在深空中引入了混合RF-FSO系统以及混合LPPM-BPSK-SIM调制。在不同太阳风波动的环境中,对比分析了采用混合RF-FSO系统与FSO系统的误码率特性。仿真结果表明,深空通信中,采用混合RF-FSO系统的误码率低于传统FSO系统。当采用混合LPPM-BPSK-SIM时,系统性能又得到进一步提升。
In order to improve the quality of deep space communication,a mixed RF-FSO system and hybrid LPPM-BPSK-SIM scheme were introduced in deep space.The bit error rate of the hybrid RF-FSO system and the FSO system were compared and analyzed under the impact of solar wind fluctuation.The simulation results indicate that the deep space communication system achieves better bit error rate performance by using hybrid RF-FSO system,and the system performance can be further enhanced by adopting hybrid LPPM-BPSK-SIM.
