通过发送/接收延迟对抗气泡引起的损伤的鲁棒UOWC系统
Robust UOWC systems against bubble-induced impairments via transmit/receive diversities
摘要:
系统研究了不同气泡尺寸和位置对水下无线光通信系统性能的影响。通过使用不同的发送和接收分集,我们调查的有效性,发送/接收分集的缓解泡沫引起的损害UOWC链路。在使用重复编码(RC)和最大比合并(MRC)的2 × 2 MIMO的帮助下,实现了鲁棒的780-Mbit/s UOWC传输。相应的中断概率可以显着降低,从34.6%的系统没有分集到小于1%。
英文摘要:
We systematically investigate the bubble-induced performance degradation for underwater wireless optical communication (UOWC) with different bubble sizes and positions. By using different transmit and receive diversities, we investigate the effectiveness of transmit/receive diversity on the mitigation of the bubble-induced impairment to the UOWC link. With the help of a 2 by 2 MIMO using repetition coding (RC) and maximum ratio combining (MRC), a robust 780-Mbit/s UOWC transmission is achieved. The corresponding outage probability can be significantly reduced from 34.6% for the system without diversity to less than 1%.
