Achievable Second-Order Asymptotics for MAC and RAC with Additive Non-Gaussian Noise
Yiming Wang, Lin Bai, Zhuangfei Wu +1
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 near…

The Dispersion of Broadcast Channels With Degraded Message Sets Using Gaussian Codebooks
Zhuangfei Wu, Lin Bai, Jinpeng Xu +2
We study the two-user broadcast channel with degraded message sets and derive second-order achievability rate regions. Specifically, the channel noises are not necessarily Gaussian…

Successive Refinement of Shannon Cipher System Under Maximal Leakage
Zhuangfei Wu, Lin Bai, Lin Zhou
We study the successive refinement setting of Shannon cipher system (SCS) under the maximal leakage secrecy metric for discrete memoryless sources under bounded distortion measures…
