Playing games with multiple access channels [PDF]
Nature Communications, 2020 AbstractCommunication networks have multiple users, each sending and receiving messages. A multiple access channel (MAC) models multiple senders transmitting to a single receiver, such as the uplink from many mobile phones to a single base station.

Homologous Codes for Multiple Access Channels [PDF]
IEEE Transactions on Information Theory, 2017 Building on recent development by Padakandla and Pradhan, and by Lim, Feng, Pastore, Nazer, and Gastpar, this paper studies the potential of structured nested coset coding as a complete replacement for random coding in network information theory. The roles of two techniques used in nested coset coding to generate nonuniform codewords, namely, shaping ...

Hierarchical Beamforming in Random Access Channels [PDF]
2021 IEEE Global Communications Conference (GLOBECOM), 2021 Managing a massive number of terminals in a contention-based multiple access is challenging due to its intrinsic limited efficiency. For example, in the random access channel considered in LTE-A and 5G NR, Base Station (BS) is just aware of the collided and non-collided preambles.

Multi-Round Contention in Wireless LANs with Multipacket Reception [PDF]
, 2010 Multi-packet reception (MPR) has been recognized as a powerful capacity-enhancement technique for random-access wireless local area networks (WLANs). As is common with all random access protocols, the wireless channel is often under-utilized in MPR WLANs.
