Clock Synchronization in Wireless Sensor Networks: An Overview
TL;DR: This paper reviews the existing clock synchronization protocols for WSNs and the methods of estimating clock offset and clock skew in the most representative clock synchronization Protocol for W SNs.
Book ChapterDOI
Uplink Interference Adjustment for Mobile Satellite Service in Multi-beam Environments
TL;DR: The simulator which analyzes uplink interference of a user link, among interferences that can occur when reuse frequencies to make efficient use of the limited frequency resources in multi-beam satellite environments, is designed.
Proceedings ArticleDOI
Performance Comparison of Time-Frequency Analysis Methods for Radar Signature Analysis
In-Sik Choi,Ill-Keun Rhee +1 more
TL;DR: Comparisons of four different time-frequency analysis techniques applied to the scattering analysis of radar targets show that the EAWT is the best technique to analyze the scattering centers and resonance frequency simultaneously.
Proceedings ArticleDOI
Signal Parameter Extraction via Component Cancellation Using Evolutionary Programming
TL;DR: Comparisons with root-MUSIC are presented to illustrate the superiority of the proposed SPECC algorithm, which has robustness to noise and high resolution in DOA estimation.
Proceedings ArticleDOI
Improved DOA estimation of correlated signals in correlated antenna noises environment
Ill-Keun Rhee,Hee-Soo Kim +1 more
TL;DR: A high resolution direction-of-arrival (DOA) algorithm is presented which can effectively estimate highly correlated multiple signals in the presence of correlated antenna array noises at the receiver by combining the forward/backward spatial smoothing algorithm with the second-order technique.
