RESEARCH EXPERIENCES

2009-present, graduate research assistant in Department of Electrical and Computer Engineering

Colorado State University, Fort Collins, CO, USA

Project 1: Waveform design for active sensing (with Prof. Ali Pezeshki).

(1a) Waveform design for Doppler resilience : Develop a general framework for designing Doppler re-

silient illuminations through coordination of phase coded component waveforms across time, frequency,

and apertures. With proper signal processing at the receiver, the radar point-spread function can be

range-sidelobe free inside some Doppler band around zero Doppler axis. This enables us to bring out

weak targets of the sidelobes generated by nearby strong re ectors that are moving at a di erent speed.

(1b) Waveform design for interference cancelation : Develop a framework for jointly designing trans-

mitters (waveform) and receivers ( lters and MVDR beamformer) of MIMO radars. The goal is to

suppress the interference plus noise power contributed by clutters and jammers.

Project 2: Optical imaging (with Prof. Randy Bartels and Ali Pezeshki).

Exploit compressed sensing as a principle of the ultra-fast line-scanned optical imaging with a single-

pixel detector. The considered system can work at a broader frequency range compared to the imaging

systems based on CCD/CMOS detectors. The illumination eld is generated by spinning a mask disc,

and does not require physically replacing masks. For objects with a sparse or compressible representa-

tion, the imaging acquisition speed of compressed sensing can be much faster than that of the raster

scan. The sensitivity of compressed sensing imaging to the misfocus e ect is also evaluated.

Project 3: Complex-valued statistical signal processing (with Prof. Louis L. Scharf).

Propose a class of widely linear complex Kalman lters (WLCKF) which can deal with the dynamical

models in which the complex-valued states and measurements are improper (correlated with their com-

plex conjugates). Compared to the conventional complex KF, a WLCKF exploits the complementary

covariances and can signi cantly improve the estimation performance. Develop an approach to generate

complex sigma-points for unscented WLCKFs that can carry the full rst and second order statistical

information of improper states.

2008-2009, undergraduate research assistant in Institute of Wireless Communication Technology

Shanghai Jiao Tong University, Shanghai, China

Project: Physical-layer resource allocation in OFDMA multi-hop networks (with Prof. Meixia Tao).

Study the joint allocation of three types of resources, namely, power, subcarriers and relay nodes,

in multi-relay assisted, dual-hop, and amplify-and-forward cooperative OFDM systems. Investigate

a subcarrier-pair based resource allocation that seeks the joint optimization of subcarrier pairing,

subcarrier-pair-torelay assignment, and power allocation. The proposed low-complexity algorithm is

asymptotically optimal at su ciently large number of subcarriers.

2007-2008, undergraduate research assistant in Institute of Wireless Communication Technology

Shanghai Jiao Tong University, Shanghai, China

Project: Wireless RFID reader design (with Professor Hui Yu).

Implement C-programming codes on a ARM development board which connects a RFID terminal chip

with the remote server. Participate in the transplantation of wireless USB adapter drivers onto an

embedded Linux operating system.
