Abstract
One WLAN cell results in unintentional interference to the adjacent cells using the channel of which center frequency is insufficiently separated. The interference affects the adjacent cells as partial band jamming (PBJ). This paper presents the effect of partial band jamming on orthogonal frequency division multiplexing (OFDM) systems. PBJ is modeled on the rectangular spectrum with uniformly distributed random phase over [0, 2π). An upper bound of 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. Finally, coding gain over partial band jamming is analyzed in OFDM-based wireless local area network (WLAN).
