Prediction based multi-antenna single-receiver mobile terminal

Abstract

We study a multi-antenna single-receiver mobile terminal for interference reduction in a TDMA system. The antenna system consists of two antenna elements where the phase and amplitude of one antenna signal is altered prior to RF combining. The system therefore requires only a single receiver chain. We propose a new basis expansion method for predicting the combiner weight and we show that the proposed algorithm has improved performance compared to a recently proposed method. The evaluation of the algorithm by simulation is based on measurements at 1.8 GHz by a two-antenna mobile terminal carried by different users.
