Achievable Second-Order Asymptotics for MAC and RAC with Additive Non-Gaussian Noise

Y Wang, L Bai, Z Wu, L Zhou - arXiv preprint arXiv:2410.10312, 2024 - arxiv.org
We first study the two-user additive noise multiple access channel (MAC) where the noise
distribution is arbitrary. For such a MAC, we use spherical codebooks and either joint …

On the Second Order Asymptotics of Covert Communications over AWGN Channels

Y Xinchun, S Wei, SL Huang… - ICC 2024-IEEE …, 2024 - ieeexplore.ieee.org
This work tackles the asymptotics of the maximal throughput of covert communications over
AWGN channels when the covert metric is Kullback-Leibler divergence (KL divergence). It is …
