2017 IEEE International Symposium on Information Theory (ISIT), 2017 OR multi-access channel is a simple model where the channel output is the Boolean OR among the Boolean channel inputs. We revisit this model, showing that employing Bloom filter, a randomized data structure, as channel inputs achieves its capacity region with joint decoding and the symmetric sum rate of $\ln 2$ bits per channel use without joint ...

The Strongly Asynchronous Massive Access Channel
Entropy, 2022 This paper considers the Strongly Asynchronous, Slotted, Discrete Memoryless, Massive Access Channel (SAS-DM-MAC) in which the number of users, the number of messages, and the asynchronous window length grow exponentially with the coding blocklength with

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.

A predefined channel coefficients library for vehicle-to-vehicle communications [PDF]
, 2015 It is noticeable that most of VANETs communications tests are assessed through simulation. In a majority of simulation results, the physical layer is often affected by an apparent lack of realism.

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.
