State Estimation in Smart Distribution System With Low-Precision Measurements
Jung-Chieh Chen, Hwei-Ming Chung, Chao-Kai Wen +2
Efficient and accurate state estimation is essential for the optimal management of the future smart grid. However, to meet the requirements of deploying the future grid at a large…
Location Identification of Power Line Outages Using PMU Measurements with Bad Data
Wen-Tai Li, Chao-Kai Wen, Jung-Chieh Chen +3
The use of phasor angle measurements provided by phasor measurement units (PMUs) in fault detection is regarded as a promising method in identifying locations of power line outages…
On Sparse Vector Recovery Performance in Structurally Orthogonal Matrices via LASSO
Chao-Kai Wen, Jun Zhang, Kai-Kit Wong +2
In this paper, we consider a compressed sensing problem of reconstructing a sparse signal from an undersampled set of noisy linear measurements. The regularized least squares or le…
Message Passing Algorithm for Distributed Downlink Regularized Zero-forcing Beamforming with Cooperative Base Stations
Chao-Kai Wen, Jung-Chieh Chen, Kai-Kit Wong +1
Base station (BS) cooperation can turn unwanted interference to useful signal energy for enhancing system performance. In the cooperative downlink, zero-forcing beamforming (ZFBF)…
A Deterministic Equivalent for the Analysis of Non-Gaussian Correlated MIMO Multiple Access Channels
Chao-Kai Wen, Guangming Pan, Kai-Kit Wong +2
Large dimensional random matrix theory (RMT) has provided an efficient analytical tool to understand multiple-input multiple-output (MIMO) channels and to aid the design of MIMO wi…
A Deterministic Equivalent for the Analysis of Small Cell Networks
Chao-Kai Wen, Guangming Pan, Jung-Chieh Chen +1
To properly reflect the main purpose of this work, we have changed the paper title to: A Deterministic Equivalent for the Analysis of Non-Gaussian Correlated MIMO Multiple Access C…
