Performance analysis of the IEEE 802.11G waveform transmitted over a fading channel with pulse-noise interference

The performance of the most promising wireless local area network (WLAN) standards today, IEEE 802.11g, which specifies orthogonal frequency-division multiplexing in order to avoid multi-path effects and at the same time achieve high data rates, was examined in this thesis. We investigated four different receivers and analyzed their performance with Viterbi soft decision decoding when the signal was transmitted over a slow, flat fading Nakagami channel for AWGN only, as well as for AWGN plus pulse-noise interference. The implementation of forward error correction coding with soft decision decoding improves the performance compared to uncoded signal if pulse-noise interference is not present. The scenarios when no side information is available (linear-combining receiver), when perfect side information is available (noise-normalizing receiver), and two alternatives to the noise-normalized receiver with much coarser side information (modified noise-normalized receiver and noise-normalized receiver with normalization error) are examined. All the scenarios are examined for various fading and interference conditions. The performance of the noise-normalized receiver is, as expected, much improved compared to the linear-combining receiver when PNI is present. Finally, the noise-normalized receiver with normalization error achieves the same or better performance than the noise-normalized receiver without the exact interference noise power.
