仿真结果表明,经过光电探测器选择后,这两种方案都能有效地消除小区间干扰的影响。 |
The simulation results show that after the Photodetector Selection(PDS), both schemes can effectively eliminate the influence of inter-cell interference. |

当用户处于干扰区时,动态小区方案的误比特率(BER)性能更优,但是其计算复杂度较高。 |
When the user is in the interference zone, the dynamic cell scheme has better Bit Error Rate(BER) performance at the cost of higher computational complexity. |

当用户都处于非干扰区时,这两种方案的BER性能相同。 |
The BER performance of the two schemes is similar when the users are in the non-interference zone. |

针对水下无线光通信系统中无法兼顾聚光效率和光斑均匀性的问题,文章设计了一种复合折反式接收天线。 |
Aiming at the problem that the concentrating efficiency and spot uniformity cannot be taken into account in underwater wireless optical communication system, a composite refractive receiving antenna is designed in this paper. |

仿真结果表明,传统的菲涅尔透镜聚光效率只有58. 725%,而新设计的复合折反式接收天线聚光效率达到86. 557%。 |
The simulation results show that the concentrating efficiency of the traditional Fresnel lens is only 58. 725%, while that of the newly designed composite refractive antenna is 86. 557%. |

在保证高聚光效率的情况下,光斑的均匀性也较好,均匀度为0. 6593。 |
Moreover, the uniformity of the spot is also good, with the uniformity of 0. 6593 under the condition of ensuring high concentration efficiency. |

随后分析了平行光源在不同角度入射时聚光效率和光斑位置偏移的变化, |
Then the change of focusing efficiency and spot position offset of parallel light source at different incident angles is analyzed. |

发现菲涅尔透镜在入射角为2°时聚光效率就只有3.5822%; |
It is found that the focusing efficiency of Fresnel lens is only 3. 5822% at 2 °incident angle, |

而文章所设计的复合折反式接收天线在入射角度为1.5°时,聚光效率仍可以达到50%以上,入射角度在4°时仍能检测到光斑。 |
while the focus efficiency of the composite refractive antenna designed in this paper can still reach more than 50% when the incident angle is 1. 5 °, and the spot can still be observed when the incident angle is 4 °. |
