Interference modeling and analysis for optical wireless communication

The optical wireless communication (OWC) system can be distorted by inter symbol interference(ISI) and background noise such as the ambient noise from the lighting etc. Detailed ISI and ambient noise modeling according to different geometry setup can help OWC systems achieve better system performance. For a given system setup, the ISI can be approached by the unified ceiling height of a ceiling bounce model. The system performance under different ambient noise to signal ratio (ASR) can also be obtained by investigate different system parameters, e.g. data rate and bit error rate (BER). The interference related parameters were discussed and analyzed under a given geometry setup, the performance were simulated using a pulse position and amplitude modulation (PAPM) scheme. The simulation results showed a generalized interference model under specific type of interference can be derived, and can be further employed for similar OWC systems.
