Abstract

Wireless Local Area Network (WLAN) has been one of the great communications technology success stories of the past few years. IEEE's standardization of WLAN has been extended to a family of standards. IEEE 802.11g, based on Orthogonal Frequency Division Multiplexing (OFDM), is a very popular standard for its capability of high data rate communication up to 54Mbps at the 2.4 GHz Industrial, Scientific and Medical (ISM) band. As the number of consumer devices designed for the ISM band is getting higher, co-channel interference has been identified as the major hindrance to the performance of WLAN devices. In this paper, a method of combating co-channel interference employing smart antenna technique is presented. We employ the Minimum Mean Square Error (MMSE) criterion to perform beamforming. We present simulation results that demonstrate performance improvement at the presence of co-channel interference.
