Downlink Transmitting Array for Cancellation of Destructive Multipath Interference in Indoor Environment

A smart antenna system at indoor base stations is proposed and its performance capabilities verified. The theory of operation is derived using the reciprocity theorem and the radio signal processing. It is shown that such an array can remove deep fades due to destructive multipath interference at the terminal antenna side. The proposed antenna array is tested on theoretical Rayleigh channel model as well as on measured radio channel, from measurements within a test room at 450 MHz.
