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
