Abstract :
Bluetooth systems result in unintentional interference to OFDM systems using industry, science and medical (ISM) bands. The performance degradation of orthogonal frequency division multiplexing (OFDM) systems from Bluetooth interference is analyzed numerically. Bluetooth interference is modeled on partial band jamming with a rectangular spectrum. Bit error probability (BEP) performance based on the effective signal-to-noise power ratio (SNR) is provided for OFDM systems in Rayleigh fading channels in addition to AWGN. Additionally, coding gain over Bluetooth interference is evaluated for an OFDM-based wireless local area network (WLAN) in IEEE 802.11g.
