Understand-Before-Talk (UBT): A Semantic Communication Approach to 6G Networks
Shiva Raj Pokhrel, Jinho Choi
In Shannon theory, semantic aspects of communication were identified but considered irrelevant to the technical communication problems. Semantic communication (SC) techniques have…
On Throughput Bounds of NOMA-ALOHA
Jinho Choi
In this paper, we focus on the throughput of random access with power-domain non-orthogonal multiple access (NOMA) and derive bounds on the throughput. In particular, we demonstrat…
Next Generation Mega Satellite Networks: Opportunities, Challenges, and Performance
Bassel Al Homssi, Akram Al-Hourani, Ke Wang +5
Digital connectivity has become the foundation of prosperity and an essential need for functioning societies. Despite this dependence, limitation on Internet access remains a preva…
Communication-Efficient Distributed SGD using Preamble-based Random Access
Jinho Choi
In this paper, we study communication-efficient distributed stochastic gradient descent (SGD) with data sets of users distributed over a certain area and communicating through wire…
Performance Analysis of 2-Step Random Access with CDMA in Machine-Type Communication
Jinho Choi
There is a growing interest in the transition from 4-step random access to 2-step random access in machine-type communication (MTC), since 2-step random access is well-suited to sh…
Grant-Free Random Access in Machine-Type Communication: Approaches and Challenges
Jinho Choi, Jie Ding, Ngoc Phuc Le +1
Massive machine-type communication (MTC) is expected to play a key role in supporting Internet of Things (IoT) applications such as smart cities, smart factory, and connected vehic…
