Abstract	Due to the coexistence of the Bluetooth and IEEE 802.11g at the ISM band, the performance of the IEEE 802.11g is deteriorated by the Bluetooth interference. This paper evaluates the performance of a smart antenna system applied to an IEEE 802.11g system in the presence of Bluetooth interference environment. The proposed smart antenna system utilizes the spectral spatial smoothing which uses the multi-carrier transmission of an OFDM system to decorrelate the correlation of the received signals and span the signal space. The DOA estimation algorithms can use the signal space derived by spectral spatial smoothing to estimate the DOAs of the received signals and the DOA based beamforming algorithms generate the weighting vector to mitigate the multipath fading, increase the diversity gain, and suppress the co-channel interference of different devices. The simulation results show that the performance of the IEEE 802.11g with the proposed smart antenna system is much better than that without the proposed smart antenna system when the Bluetooth interference exists.
