A deep-learning-based MAC for integrating channel access, rate adaptation, and channel switch

open access: yesDigital Communications and Networks
With increasing density and heterogeneity in unlicensed wireless networks, traditional MAC protocols, such as Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) in Wi-Fi networks, are experiencing performance degradation. This is manifested

Multiple Access Channel Simulation [PDF]

open access: yes2021 IEEE International Symposium on Information Theory (ISIT), 2021
We study the problem of simulating a two-user multiple-access channel (MAC) over a multiple access network of noiseless links. Two encoders observe independent and identically distributed (i.i.d.) copies of a source random variable each, while a decoder observes i.i.d. copies of a side-information random variable.
