Welcome to	Xiang He's	Homepage!
		Currently I am a PhD student in the Department of Electrical Engineering in Penn State University. My PhD advisor is Dr. Aylin Yener and I am a member of the Wireless Communication and Networking(WCAN) Group. My research interests include secrecy and authentication, information theory, coding theory, queuing theory, optimization techniques, distributed detection and estimation. I obtained my MS degree of Shanghai Jiao Tong University. During my master study, I worked on the design and high speed FPGA implementation of channel encoder/decoder and MIMO detectors.

Codes

1. prepare.pl: When writing a paper, most of us accumulate a lot of files which are not referenced by the latex code. Sometimes we wish to keep these files, including figures, proof, programs which may be useful later. However, this leads to a messy file folder, which becomes a problem when we want to send the latex code to someone else without these unreferenced files. This small segment of perl code hopefully makes this task easier. It copies the latex code, and the files it referenced to a given folder.
