| 51987 | 考虑了4种合并方案，即等增益合并(EGC)、选择合并(SBC)、最大比合并(MRC)和最小均方误差(MMSE)合并。 | Four combination schemes are considered, namely Equal Gain Combining(EGC), Select Best Combining(SBC), Maximum Ratio Combining(MRC), Minimum Mean Square Error(MMSE) combining. |
| 51988 | 作为对比，也仿真了单PD接收机(SR)和传统角度分集接收机(ADR)的室内信干噪比(SINR)分布及ASE性能。 | In comparison, the indoor Signal to Interference and Noise Ratio(SINR) distribution and ASE performance of Single PD Receiver(SR) and traditional Angle Diversity Receiver(ADR) are also simulated. |
| 51989 | 仿真结果表明，2FOV-ADR极大地改善了室内SINR分布， | It is found that 2FOV-ADR greatly improves the indoor SINR distribution. |
| 51990 | 相比于单PD接收机和传统ADR，小区边缘位置处的SINR分别得到30和20 dB的改善， | Compared with the single PD receiver and the conventional ADR, the SINR at the cell edge position is improved by 30 and 20 dB, respectively, |
| 51991 | 并且在不同用户数下，2FOV-ADR都具有最高的ASE。 | and the 2FOV-ADR has the highest ASE at different user numbers. |
| 51992 | 因此，2FOV-ADR可以实现比单PD接收机和传统ADR更优的性能。 | Therefore, 2FOV-ADR can achieve better performance than single PD receivers and traditional angle diversity receivers. |
| 51993 | 为了对西藏人烟稀少地区和单跨段传输距离很长的光纤链路进行检测， | In order to monitor the fiber-optic links in Tibet, which are sparsely populated and have long transmission distances. |
| 51994 | 文章提出一种用于提高线性调频(LFM)光时域反射仪(OTDR)空间分辨率和测量距离的方法。 | This paper presents a method of improving the spatial resolution and measuring the distance of a Linear Frequency Modulated(LFM) Optical Time Domain Reflectometry(OTDR). |
| 51995 | 该方法通过产生一个调频范围为200 MHz、脉冲宽度为20μs的强度调制模拟LFM信号来实现高的空间分辨率和大的探测距离。 | The method achieves high spatial resolution and large detection distance by generating an intensity modulated analog chirp signal with a frequency range of 200 MHz and a pulse width of 20 μs. |
| 51996 | 使用该方法在西藏地区的实际光纤传输链路中进行了实验测试， | Experiments are carried out on the actual fiber-optic transmission link in Tibet using this method. |
