Economical time domain smart antenna for the performance improvement of wi-fi hub

Abstract

Function of smart antennas enhancing the OFDM based WLAN's immunity to multipath fading environments has been summarized. Time domain implementation of smart antenna algorithm(pre-FFT algorithm) has been explained and a simple modification associated with the weight update of pre-FFT algorithm has been proposed Through computer simulations, the performances of the both algorithms have been shown and it was observed that the proposed algorithm contributed to obtain acceptable performance in multipath fading scenario. © 2014 Springer-Verlag Berlin Heidelberg.
