MIMO-OFDM systems for IEEE 802.11n WLAN Standard using ESPAR antenna

Abstract

This paper proposes MIMO-OFDM system for IEEE 802.11n using electronically steerable parasitic array radiator (ESPAR) antenna. Although the 2 x 2 MIMO-OFDM system is capable of doubling the capacity without expanding the occupied frequency bandwidth, we can’t obtain the additional diversity gain using the linear MIMO decomposition method. The proposed method can improve the bit error rate performance of the MIMO-OFDM receiver by making efficient use of ESPAR antenna. Computer simulation result shows that the proposed scheme gives the additional diversity gain.
