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…

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…

Efficient User Scheduling for Uplink Hybrid Satellite-Terrestrial Communication
Lina Zhu, Lin Bai, Lin Zhou +1
Due to increasing demands of seamless connection and massive information exchange across the world, the integrated satellite-terrestrial communication systems develop rapidly. To s…
