We examine the effects of artificial light interference on optical systems employing dual header pulse interval modulation (DH-PIM). This interference can be reduced using high pass filtering (HPF). However, the HPF generates an interference called baseline wander. We study the effects of changing the HPF cut-on frequency in the absence and presence of multipath propagation. Results show that depending on the value of the HPF cut-on frequency, the severity of baseline wander will vary and thus there is a trade off between the extent of artificial light interference rejection and the severity of baseline wander.
