Autor: ZHANG ZhiXing, REN YanPing, GAO Heng, LI ZhongWen, LU JinSheng, CAI ZhenBing, ZHU MinHao

Publikováno v: Jixie qiangdu, Vol 43, Pp 300-307 (2021)

Plasma nitriding of the quenching and tempering 42 CrMo steel was carried out at 530 ℃ using two different N2-H2 atmospheres: 3% N2 and 80% N2,which prepared two types of samples with different compound layers,ε + γ’ compound-phase andγ’ sin

Rethinking Grant-Free Protocol in mMTC

Autor: Zhu, Minhao, Sun, Yifei, You, Lizhao, Wang, Zhaorui, Liu, Ya-Feng, Cui, Shuguang

This paper revisits the identity detection problem under the current grant-free protocol in massive machine-type communications (mMTC) by asking the following question: for stable identity detection performance, is it enough to permit active devices
