Current Interests

My research interests span broad areas of signal processing and communication and information theories for wireless systems and networks. Current topics of interest include:
  • Spectrum coexistence
  • Cross-layer security
  • Low-resolution analog to digital converter (ADC)
  • Full-duplex and cognitive radio
  • Capacity-approaching yet low complexity designs for multi-user wireless networks
  • Two-way relay communications
  • Fundamental limits and practical code/signal designs for non-Gaussian channels
  • Coded modulation and iterative decoding

Other Research Topics

  • Security in Smart Grid

Selected Past Contributions

  • A low complexity transceiver structure that practically eliminates adverse effects of fading in wireless communications
  • Subcarrier grouping and precoding techniques for OFDM/OFDMA-based systems to achieve an excellent error performance while keeping the system’s complexity at minimum
  • A powerful yet simple coded modulation technique in MIMO systems for near capacity limit performance, applicable to LTE-Advanced
  • Optimal Amplify-and-Forward (AF) protocols for wireless relay networks
