IQ Gain Imbalance Measurement for OFDM based Wireless Communication Systems
Arslan,HuseyinUSF
In this paper, IQ gain imbalance for OFDM based multi-carrier modulation techniques is studied. The effect of gain mismatch in IQ modulator will be investigated on the system and receiver performance. Estimation and measurement of IQ gain mismatch at the receiver using baseband digital signal processing techniques will be discussed.

Dr. Arslan has received his PhD. degree in 1998 from Southern Methodist University (SMU), Dallas, Tx. From January 1998 to August 2002, he was with the research group of Ericsson Inc., NC, USA, where he was involved with several project related to 2G and 3G wireless cellular communication systems. Since August 2002, he has been with the Electrical Engineering Dept. of University of South Florida. He has also been working for Anritsu Company, Morgan Hill, CA (as a visiting professor during the summer of 2005) as a part-time consulting since August 2005. Dr. Arslan’s research interests are related to advanced signal processing techniques at the physical layer, with cross-layer design for networking adaptivity and Quality of Service (QoS) control. More specifically, he is interested in signal processing techniques for wireless communication systems including modulation and coding, interference cancellation and multi-user signal detection, channel estimation and tracking, equalization, soft information generation, adaptive receiver and transmission technologies etc. He is interested in many forms of wireless technologies including cellular, wireless PAN/LAN/MANs, fixed wireless access, and specialized wireless data networks like wireless sensors networks and wireless telemetry. The current research interests are on UWB, OFDM based wireless technologies with emphasis on WIMAX, and cognitive and software defined radio. He has served as technical program committee member, session and symposium organizer in several IEEE conferences. He is editorial board member for Wireless Communication and Mobile Computing journal, and was technical program co-chair of IEEE wireless and microwave conference 2004. Dr. Arslan is a senior member of IEEE.
