Capacity Bounds and High-SNR Characterization for MIMO-OWC Channels Under Average-Power Constraint
Sufang Yang, Liang Xia, Longguang Li +7
This paper investigates the capacity of multipleinput multiple-output (MIMO) optical wireless communication (OWC) channels under a total average-power constraint. Since different n…
Secrecy Capacity Analysis and Beamforming Optimization for MIMO-VLC Wiretap Channels
Sufang Yang, Longguang Li, Jintao Wang +5
This paper investigates a multiple-input multipleoutput (MIMO) visible light communication (VLC) wiretap channel consisting of a transmitter, a legitimate receiver, and an eavesdro…
On the Low-SNR Asymptotic Capacity of Two Types of Optical Wireless Channels under Average-Intensity Constraints
Longguang Li
In this paper, we study two types of optical wireless channels under average-intensity constraints. One is called the Gaussian optical intensity channel, where the channel output m…
On the Capacity Region of Optical Intensity Broadcast Channels
Sufang Yang, Longguang Li, Jintao Wang
This paper investigates the capacity region of the optical intensity broadcast channels (OI-BCs), where the input is subject to a peak-intensity constraint, an average-intensity co…
Distribution Decomposition and Sum-Capacity Results of Two-User Optical Intensity Multiple Access Channels
Longguang Li, Ru-Han Chen, Jing Zhou
This paper investigates the sum-capacity of two-user optical intensity multiple access channels with per-user peak- or/and average-intensity constraints. By leveraging tools from t…
On the Capacity of MISO Optical Intensity Channels With Per-Antenna Intensity Constraints
Ru-Han Chen, Longguang Li, Jian Zhang +2
This paper investigates the capacity of general multiple-input single-output (MISO) optical intensity channels (OICs) under per-antenna peak- and average-intensity constraints. We…
Tradeoff between Diversity and Multiplexing Gains in Block Fading Optical Wireless Channels
Sufang Yang, Longguang Li, Haoyue Tang +1
The diversity-multiplexing tradeoff (DMT) provides a fundamental performance metric for different multiple-input multiple-output (MIMO) schemes in wireless communications. In this…
On the Capacity of MIMO Optical Wireless Channels
Longguang Li, Stefan M. Moser, Ligong Wang +1
This paper studies the capacity of a general multiple-input multiple-output (MIMO) free-space optical intensity channel under a per-input-antenna peak-power constraint and a total…
On the Capacity of Fading Channels with Peak and Average Power Constraints at Low SNR
Longguang Li, Lokman Sboui, Zouheir Rezki +1
The capacity of fading channels under peak and average power constraints in the low-SNR regime is investigated. We show that the capacity scales essentially as ${C \approx A \ \tex…
Second Order Asymptotics for Communication under Strong Asynchronism
Longguang Li, Aslan Tchamkerten
The capacity under strong asynchronism was recently shown to be essentially unaffected by the imposed output sampling rate and decoding delay ---the elapsed time between whe…
