Dynamic Hierarchical Birkhoff-von Neumann Decomposition for All-to-All GPU Communication
Yen-Chieh Wu, Cheng-Shang Chang, Duan-Shin Lee +1
All-to-all GPU communication is a critical bottleneck in large-scale training clusters, where completion time is constrained by per-port bandwidth and can be severely impacted by t…
Using Locality-sensitive Hashing for Rendezvous Search
Guann-Yng Jiang, Cheng-Shang Chang
The multichannel rendezvous problem is a fundamental problem for neighbor discovery in many IoT applications. The existing works in the literature focus mostly on improving the wor…
Resource Allocation for URLLC and eMBB Traffic in Uplink Wireless Networks
Duan-Shin Lee, Cheng-Shang Chang, Ruhui Zhang +1
In this paper we consider two resource allocation problems of URLLC traffic and eMBB traffic in uplink 5G networks. We propose to divide frequencies into a common region and a gran…
A Hierarchical Stitching Algorithm for Coded Compressed Sensing
Yi-Jheng Lin, Chia-Ming Chang, Cheng-Shang Chang
Recently, a novel coded compressed sensing (CCS) approach was proposed in [1] for dealing with the scalability problem for large sensing matrices in massive machine-type communicat…
ALOHA Receivers: a Network Calculus Approach for Analyzing Coded Multiple Access with SIC
Tzu-Hsuan Liu, Che-Hao Yu, Yi-Jheng Lin +2
Motivated by the need to hide the complexity of the physical layer from performance analysis in a layer 2 protocol, a class of abstract receivers, called Poisson receivers, was rec…
Poisson Receivers: a Probabilistic Framework for Analyzing Coded Random Access
Che-Hao Yu, Lin Huang, Cheng-Shang Chang +1
In this paper, we develop a probabilistic framework for analyzing coded random access. Our framework is based on a new abstract receiver (decoder), called a Poisson receiver, that…
A Quasi-random Algorithm for Anonymous Rendezvous in Heterogeneous Cognitive Radio Networks
Cheng-Shang Chang, Yeh-Cheng Chang, Jang-Ping Sheu
The multichannel rendezvous problem that asks two secondary users to rendezvous on a common available channel in a cognitive radio network (CRN) has received a lot of attention lat…
