An equalization technique for indoor IR wireless LANs

Original results are presented that evaluate the dispersion in the optical diffuse infrared channel and its effects on optical orthogonal codes (OOCs). A new equalization technique is introduced and analyzed in the context of this channel. The method is shown to be effective in reducing the resultant intersymbol interference (ISI). Illustrative examples are given on an isolated pulse and on a typical OOC. The results indicate that good performance can be achieved with minimum hardware overheads. © 1995 John Wiley & Sons, Inc.
