Research Interests

I am primarily interested in research on communications/information theory and its applications to wireless communication systems.

My current research interests are as follows:

  • Sub-6 GHz Massive MIMO - channel estimation, power control and pilot contamination analysis

  • Non-Orthogonal Multiple-Access (NOMA) - channel estimation and practical transmission impairments

  • Dynamic TDD transmission designs for heterogeneous cellular systems with spectrum-sharing

  • Millimeter-wave communication systems - channel estimation, hydrid-precoder designs and fundamental performance analysis

  • Physical layer security - detection and mitigation of active pilot attacks

  • Deep learning for physical-layer communication designs

  • Wireless energy harvesting for IoTs - Non-linear effects of energy harvesting circuitry

  • Simultaneous wireless information and power transfer - Fundamental energy-rate trade-off analysis with estimated channels

  • Cooperative MIMO relay networks - impact of massive MIMO with imperfectly estimated channels
