Abstract

In this paper, the performance of dual header pulse interval modulation (DH-PIM) employing a linear zero forcing equaliser (L-ZFE) in diffused optical wireless indoor environment is presented. The work is based on the ceiling bounce channel model and the Monte Carlos simulation. A 3-tap L-ZFE is used and the results are compared with unequalised DH-PIM as well as with digital pulse interval modulation (DPIM), pulse position modulation (PPM) and on-off keying (OOK) schemes. The power penalty due to intersymbol interference is presented for each of the signalling techniques. The results presented show that equalisation does reduce the error probability and power requirements of high data rate DH-PIM in a highly dispersive environments.
