考虑到碰撞由隐藏的终端引起了，这由于光设备的狭窄的横梁是特别地严肃的，多包接收(MPR ) 被介绍为 IEEE 减轻碰撞 802.15.7 可见轻通讯(VLC ) 系统。在系统性能上探索 MPR 的影响并且调查在之间的相互作用物理( PHY )层和媒介存取控制( MAC )层，一三维( 3D )搬运人感觉的综合 PHY-MAC 分析模型多重存取/碰撞回避( CSMA/CA )为 VLC 系统， MPR 通过直角的代码顺序的使用在被实现基于 Markov 链理论被建立。产量被导出在有瑕疵的光隧道下面与 MPR 能力评估 VLC 系统的表演。结果能与 MPR 能力被用于一个 VLC 系统的表演优化。

英文摘要：

Considering that the collision caused by hidden terminal is particularly serious due to the narrow beams of optical de- vices, the multi-packet reception （MPR） is introduced to mitigate the collisions for IEEE 802.15.7 visible light com- munication （VLC） system. To explore the impact of MPR on system performance and investigate the interaction be- tween physical （PHY） layer and media access control （MAC） layer, a three dimensional （3D） integrated PHY-MAC analytical model of carrier sense muttiple access/collision avoidance （CSMA/CA） is established based on Markov chain theory for VLC system, in which MPR is implemented through the use of orthogonal code sequence. Throughput is derived to evaluate the performance of VLC system with MPR capability under imperfect optical channel. The re- sults can be used for the performance optimization of a VLC system with MPR capability.
