Efficient compression of silence part and efficient detection of end of silence part for VoIP communication under the wireless LAN environment
Shun Kato, Takashi Imaizumi (Chiba Univ.) IN2018-145
Abstract (in Japanese) (See Japanese page) 
(in English) Under the wireless LAN environment, when priority control using HCCA system is performed if a lot of sound communication terminals connected to single access point, there is a possibility of the degradation of the communication quality of the best effort class communication. In this paper, we make the band width efficient by compressing a silent part of sound communication. We have to detect an end of the silent period to compress silent part. We also propose Enhanced Activity Detection-Contention Free Access(EAD-CFA) for the way to make this detection efficient.
