摘　　要：针对光源阵列简化处理在无线光接入网信道建模中的适用程度进行了量化评估,具体讨论了发端阵列简化操作在不同光源阵列配置、接收端视场角、光源辐射特性下的适用表现。量化结果显示,简化处理的适用表现对视场角有很强的依赖性,仅当视场角不低于 60°时,简化对关键指标路径损耗和时延扩展特性的偏差分别被限制在153dBo和0.77ns以内。The adaptability of light source array simplification in channel modeling of wireless optical access network was evaluated, the applicable performance of this simplification to channel characterization under different transmitter configuration, different Field Of View （FOV） and different source radiation pattern was discussed. Simulation results illustrate that the applicable performance has a strong dependence on the FOV, only when the FOV is no less than 60°, the induced deviation to optical path loss and root mean square delay spread are limited within 1.53 dBo and 0.77 ns, respectively.
