Research Interests

• Wireless Channel Characterization: statistically non-stationary, multi-band & multi-resolution models; current applications include air-ground channel modeling, vehicle-to-vehicle channel modeling, "micro-channel" modeling for wireless networks on chips
• Ad Hoc Communication Networks: multiple access, duplexing, & multiplexing schemes for dynamic range/rate/latency/lifetime; performance for non-stationary topologies; ad hoc network metrics
• Modulation/Detection PHY/MAC: Spread Spectrum modulations, efficient detection schemes, & reactive-bandwidth spectral overlay; Narrowband Modulation variable-bandwidth spectral overlay, co-channel interference suppression & rapid performance estimation; robust UAS transmission schemes (e.g., FBMC); V2V channel/MAC modeling
• Random Process Modeling: modeling of communication signals and their statistics
• Electromagnetics Modeling: wave propagation and antennas for communications applications; FDTD & ray tracing
