Investigation of electromagnetic noise coupling that affects packet error rates in wireless-LAN mounted printed circuit boards

摘要

This paper shows experimental results of packet error rates (PERs) in wireless-LAN mounted printed circuit boards and gives a discussion on a channel of electromagnetic noise coupling that affects the PER. We utilize the amplitude probability distribution (APD), a statistical and quantitative method for noise evaluation, to investigate the noise coupling channel. Evaluation results indicate that the noise transmitting space and coupling to an antenna cause an increase of the PER.
