Simultaneous channel estimation and signal detection in wireless ultraviolet communications combating inter-symbol-interference (2018)
Journal Article
Wei, Z., Hu, W., Han, D., Zhang, M., Li, B., & Zhao, C. (2018). Simultaneous channel estimation and signal detection in wireless ultraviolet communications combating inter-symbol-interference. Optics Express, 26(3), 3260-3270. https://doi.org/10.1364/oe.26.003260

One primary challenge in wireless ultraviolet communications (UVCs) is the inter-symbol-interference (ISI), which may block the detection of current informative signal, especially when channel-related characteristics are unknown. In this paper, we pr... Read More about Simultaneous channel estimation and signal detection in wireless ultraviolet communications combating inter-symbol-interference.

Viterbi Estimation on the Finite-State Markov Ultra-violet Channels (2017)
Presentation / Conference Contribution
Wei, Z., Hu, W., Zhang, M., Han, D., Li, B., & Zhao, C. (2017, November). Viterbi Estimation on the Finite-State Markov Ultra-violet Channels. Presented at Asia Communications and Photonics Conference 2017, Guangzhou, Guangdong

This article addresses the inter-symbol interference (ISI) of Ultraviolet (UV) communications driven by scattering effect. We model UV channel-state-information (CSI) as Markov finite-state and design Viterbi scheme to estimate informative bits.

Polar Code for Future 60 GHz Millimeter-Wave Communications (2015)
Presentation / Conference Contribution
Wei, Z., Li, B., & Zhao, C. (2014, July). Polar Code for Future 60 GHz Millimeter-Wave Communications. Presented at Third International Conference on Communications, Signal Processing, and Systems, Hohhot, Inner Mongolia

With high operating frequencies and high emission power, 60 GHz millimeter communications may suffer seriously from realistic hardware impairments. Among this, nonlinear power amplifier (PA) will significantly degrade its transmission performance. In... Read More about Polar Code for Future 60 GHz Millimeter-Wave Communications.
