Abstract

Adaptive array systems proposed for the rejection of multipath fading and additive interference in wideband indoor wireless communications need the addition of some frequency compensation methods in order to achieve their physical implementation. Spectral decomposition and the focusing technique are the two methods of frequency compensation that have been examined. Their performances are compared on the basis of the output signal-to-interference-plus-noise ratio (SINR) and the array patterns. For both techniques, the constant power algorithm (CPA) is used to adjust the adaptation weights.
