This paper presents brief account on smart antenna (SA) system. Smart or adaptive antenna arrays consist of an array of antenna elements with signal processing capability that optimizes the radiation and reception of a desired signal dynamically. SAs can place nulls in the direction of interferers via adaptive updating of weights linked to each antenna element. SAs thus cancel out most of the c...

Recently, a smart antenna, i.e., a blind adaptive antenna array, has attracted much attention to improve the capacity of a future code-division multiple-access wireless communications system. It has been demonstrated (Tanaka et al., 2000) that there is significant improvement in data demodulation through lab simulations and field experiments by employing a smart antenna of multiple elements. Ho...

Smart antennasystems have received much attention in the last few years because they can increase system capacity by dynamically tuning out interference while focusing on the intended user. In this paper, we focused our research on the performance of two kinds of smart antenna receivers. An analytical model is proposed for evaluating the BER performance using a closed-form expression. Also, for...

A smart antenna system combines multiple antenna elements with a signal processing capability to optimize its radiation and/or reception pattern automatically in response to the signal environment through complex weight selection. The weight selection process to get suitable Array factor with low Half Power Beam Width (HPBW) and Side Lobe Level (SLL) is a complex method. The aim of this task is...

This paper attempts to compare the system downlink performance of a smart antenna scheme for OFDMA that utilizes channel covariance information with an opportunistic multi-antenna scheme for OFDMA that uses fast limited feedback of the instantaneous channel condition. The schemes are evaluated by means of simulations in a low load scenario and also compared to a simple HSDPA-like scheme. The sm...
