Abstract

Abstract: Orthogonal frequency division multiplexing (OFDM), which has been widely used in the wire and wireless communication systems, is a promising technique in future wireless communications for its good performance in combating multipath fading. Based on the analysis of the basic OFDM system, an adaptive antenna array with Kalman algorithm of updating weights of antenna arrays in the frequency domain is presented in the paper. Theoretical analysis and computer simulation results show that the adaptive antenna array with the proposed algorithm has good performance in suppressing co-channel interference and can improve the receiving performance of the system.

Key words: OFDM, adaptive antenna array, beamforming
