Abstract

The performance of the dual header pulse interval modulation (DH-PIM) scheme in indoor diffuse optical wireless environments is examined. The power requirement and penalty due to intersymbol interference is analysed using the ceiling-bounce model and results are compared with other modulation schemes such as PPM and DPIM. It is shown that for given parameters, DH-PIM requires marginally higher optical power compared with PPM and DPIM, but it supports the same bit rate with much lower bandwidth requirement
