Novel half-duplex relay strategy and its resource allocation
Tongxin xuebao, 2009 Conventional time-division half-duplex relay strategies based on amplify-and-forward or decode-and-forward strategy could relieve relay nodes from full-duplex requirement but lead to degraded spectrum efficiency.

ZF-SIC Based Individual Secrecy in SIMO Multiple Access Wiretap Channel
IEEE Access, 2017 In this paper, a decoding method of joint zero-forcing and successive interference cancellation (ZF-SIC) is put forward to assist the study of the individual secrecy in the quasi-static Rayleigh fading single-input multiple-output multiple access wiretap

A Jamming-Resilient and Scalable Broadcasting Algorithm for Multiple Access Channel Networks
Applied Sciences, 2021 Multiple access channel (MAC) networks use a broadcasting algorithm called the Binary Exponential Backoff (BEB) to mediate access to the shared communication channel by competing nodes and resolve their collisions.

Source-channel coding for the multiple-access relay channel [PDF]
2011 8th International Symposium on Wireless Communication Systems, 2011 This work considers reliable transmission of general correlated sources over the multiple-access relay channel (MARC) and the multiple-access broadcast relay channel (MABRC). In MARCs only the destination is interested in a reconstruction of the sources, while in MABRCs both the relay and the destination want to reconstruct the sources.
