Smart antenna for IEEE 802.11 wireless LAN II with near field distortion compensation

Abstract

Smart antenna technology has proved to be a valuable add-in feature for communication systems. However, its application indoors, in particular to the unlicensed 2.4-GHz industrial, scientific and medical (ISM) band has not been accomplished yet, mainly due to the problem of near-field distortion that upsurges from the indoor channel characteristics at the mentioned band. We evaluate the compensation scheme to eliminate such near field distortion presented by Abren and Kohno (see Proc. of the ICT2000, vol.2, p.900-906, 2000) under the IEEE 802.11 standard's specifications.
