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…
Data-aided Sensing for Gaussian Process Regression in IoT Systems
Jinho Choi
In this paper, for efficient data collection with limited bandwidth, data-aided sensing is applied to Gaussian process regression that is used to learn data sets collected from sen…
Data-aided Sensing for Distributed Detection
Jinho Choi
In this paper, we study data-aided sensing (DAS) for distributed detection in wireless sensor networks (WSNs) when sensors' measurements are correlated. In particular, we derive a…
Explore-Before-Talk: Multichannel Selection Diversity for Uplink Transmissions in Machine-Type Communication
Jinho Choi, Jihong Park, Shiva Pokhrel
Improving the data rate of machine-type communication (MTC) is essential in supporting emerging Internet of things (IoT) applications ranging from real-time surveillance to edge ma…
An Approach to Preamble Collision Reduction in Grant-Free Random Access with Massive MIMO
Jinho Choi
In this paper, we study grant-free random access with massive multiple input multiple output (MIMO) systems. We first show that the performance of massive MIMO based grant-free ran…
