Study of Electromagnetic Noise Coupling in Wireless-LAN Communication System
This paper shows experimental results of packet error rates (PERs) in wireless-LAN mounted printed circuit boards and gives a discussion on a mechanism of electromagnetic noise coupling that affects the PER. We utilized the amplitude probability distribution (APD) to investigate the noise coupling channel. We measured magnetic near-field distribution to obtain information about a noise source. Based on measurement results, we also performed a parallel plate resonance analysis to find out an electromagnetic interference (EMI) antenna. Evaluation results indicate that noise radiates from a board edge and its coupling to an antenna causes an increase of the PER. Key words: packet error rate, noise coupling, amplitude probability distribution, magnetic near-field measurement, resonance analysis.
