Performance analysis of IEEE 802.11G receivers with erasure decoding to mitigate the effects of pulse-noise interference [electronic resource] /
Abstract (Summary)The performance of IEEE 802.11g wireless local area network (WLAN) standard receivers when the signal is transmitted over a frequency-selective, slowly fading Nakagami channel in a pulse-noise interference environment when errors-and-erasures Viterbi decoding is used is examined. The different combinations of modulation (both binary and non-binary) and convolutional code rate specified by the WLAN standard are examined. The performance obtained with errors-and-erasures decoding (EED) is compared with the performance obtained with errors-only hard decision Viterbi decoding (HHD) as well as that obtained with soft decision Viterbi decoding (SDD) for binary modulation, while for non-binary modulation, EED performance is compared with HDD performance. It was found that EED can significantly improve performance under some conditions when pulse-noise interference is present.
