Analysis of phase noise interference in Wi-Fi 802.11b signals

In this paper, the analysis of Phase Noise Interference in Wi-Fi 802.11b Signals has been achieved. This paper researches the behaviour of Wi-Fi 802.11b signal in the presence of a generic phase noise. Since all source of interference are rated in decibels (-dB), it was convenience to determined how much aggregated noise levels can create errors per frame of the Wi-Fi spectrum. The methodology employed in this work was to model a typical system in Matlab/Simulink environment and systematically introduce a phase noise component into an 802.11b Wi-Fi (channel 11) path .The result obtained showed that for values lower than about -41.5dB, the signal resisted the production of errors per sample
