Biography

Gerry Tian was a visiting professor at the CAS group, in September 2008.

I received the B.E. degree in Electrical Engineering (Automatic Control) from the University of Science and Technology of China, Hefei, China, in 1994, and the M. S. and Ph.D. degrees from George Mason University, Fairfax, VA, in 1998 and 2000 respectively. From 1994 to 1995, I studied in the graduate program of the department of Automation at Tsinghua University, Beijing, China. From 1995 to 2000, I was a graduate research assistant in the Center of Excellence in Command, Control, Communications and Intelligence (C3I) of George Mason University. Since August 2000, I have been on the faculty of Michigan Technological University, where I am a Professor.

My general interests are in the areas of signal processing, communications, detection and estimation. Specific areas of expertise have included ultra-wideband communications, MIMO systems, statistical sensor array processing, adaptive filtering, multi-target tracking, data fusion, Bayesian inference, and decision network theory and applications. Current research focuses on compressed sensing for random processes, statistical inference of network data, cognitive radio networks, and distributed wireless sensor networks. I am an elected member of the IEEE Signal Processing for Communications and Networking Technical Committee (SPCOM‐TC). I served as Associate Editor for IEEE Transactions on Wireless Communications (2002 ? 2008) and IEEE Transaction on Signal Processing (2006 ? 2009). I received a CAREER award from the National Science Foundation in 2003. I am an IEEE Fellow.

    Abstract: ... This paper develops efficient channel estimation techniques for millimeter-wave (mmWave) massive multiple-input multiple-output (MIMO) systems under practical hardware limitations, including an arbitrary array geometry and a hybrid hardware structure. Taking on an angle-based approach, this work adopts a generalized array manifold separation approach via Jacobi-Anger approximation, which transforms a non-ideal, non-uniform array manifold into a virtual array domain with a desired uniform geometric structure to facilitate super-resolution angle estimation and channel acquisition. Accordingly, structure-based optimization techniques are developed to effectively estimate both the channel covariance and the instantaneous channel state information (CSI) within a short sensing time. The different time-varying scales of channel path angles versus path gains are capitalized to design a two-step CSI estimation scheme that can quickly sense fading channels. Theoretical results are provided on the fundamental limits of the proposed technique in terms of sample efficiency. For computational efficiency, a fast iterative algorithm is developed via the alternating direction method of multipliers. Other related issues such as spurious-peak cancellation in non-uniform linear arrays and extensions to higher-dimensional cases are also discussed. Simulations testify the effectiveness of the proposed approaches in hybrid mmWave massive MIMO systems with arbitrary arrays.
