AN EQUALIZATION TECHNIQUE FOR INDOOR IR WIRELESS LANS

Original results are presented that evaluate the dispersion in the opt ical diffuse infrared channel and its effects on optical orthogonal co des (OOCs). A new equalization technique is introduced and analyzed in the context of this channel. The method is shown to be effective in r educing the resultant intersymbol interference (ISI). Illustrative exa mples are given on an isolated pule and on a typical OOC. The results indicate that good performance can be achieved with minimum hardware o verheads. (C) 1995 John Wiley & Sons, Inc.
