Welcome to my old school early 90s style website! I am a Ph.D Candidate in Department of Electrical and Computer Engineering under professor Yanyong Zhang and Dr. Rich Howard, Rutgers University. I also work closely with professor Wade Trappe and Professor Dipankar Raychaudhuri . I am a research assistant in Wireless Information Network Lab (WINLAB), where I am currently working on distributed beamforming for secret communication and wireless power transferring. My research interests are digital/analog signal processing, mathematical modelings and implementations of wireless systems.

 

PROJECTS

Secret-Focus: Ensuring confidentiality of communication is fundamental to securing the operation of a wireless system, where eavesdropping is easily facilitated by the broadcast nature of the wireless medium. By applying distributed phase alignment among distributed transmitters, we show that a new approach for assuring physical layer secrecy, without requiring any knowledge about the eavesdropper or injecting any additional cover noise, is possible if the transmitters frequently perturb their phases around the proper alignment phase while transmitting messages. This approach is readily applied to amplitude-based modulation schemes, such as PAM or QAM. We present our secrecy mechanisms, prove several important secrecy properties, and develop a real world practical secret communication system.
--This work is a byproduct of my last work, Energy-Ball. This work receives indeed good reviews. As commented by professor Zhu Han, one of the fundamental contributors in physical layer wireless security, "it is a significant work that tackles down the Achilles' heel in physical layer wireless security."
--The phase dithering technique lies at a very special sweetspot in my mind no matter how many years have gone by. The salient merit of phase dithering was discovered in a pure accident(!) by me playing the one-bit algorithm across different receivers. The exciting Eureka moment never fade. Needless to say it is an important reason I enjoy research this much.

Energy-Ball: This work presents a new wireless power transfer (WPT) approach by aligning the phases of a collection of distributed radio frequency (RF) chargers at the target receiver device. Our approach can ship energy over tens of meters, to mobile targets, and even to targets blocked by obstacles. More importantly, our approach is much safer than traditional beamforming based WPT systems by largely avoiding overheating other areas. Thanks to its advantage on safety, under the same FCC limit, our approach can be scaled up to ship higher level of energy over longer distance than using traditional beamforming approach. Such a technology can enable a large array of Internet of Things (IoT) applications and render them much more robust and long-running.
--This work is the world first real world distributed beamforming system that shows its safety merit for WPT. The idea stems from mimicking how Fresnel Zone plates focus the light at the focus point. The origin of this idea comes from a discussion with my advisor Dr. Rich Howard, who is a physicist and VP of wireless research at Bell Labs.

Auto++: In this work, we propose a real-time system that detects approaching cars by using the embedded microphones on cellphones. The target of this work is to improve pedestrian safety by alarming distracted smartphone users. Our proposed system detects cars when they are around 5.7 seconds away across different car speeds, road conditions, weathers and type of cars.
--The best part of this work is we developed a full set of features to discriminate between car sounds and other environmental sounds by pure signal processing techniques. The system is a very light weight design and requires no pre-training or calibration. It is also the first true piece of work brought me into research.

I love classical music. I like Johannes Brahms, Gustav Mahler and Wolfgang Amadeus Mozart. Besides collecting great recordings in history, I also enjoy live classical music concerts at NJSO and NYPhil. It is the reason interests me in signal processing since years back.

I am also an audiophile, but not a typical audiophile you may know. Here is a personal statement of my audio experience and philosophy.
