Annex B

Dr. Liang Ying Chang

Dr. Liang Ying Chang has made significant contributions to the filed of cognitive radio networking and communications, particularly in spectrum sensing, sensing-access tradeoff design and multi-antenna solutions for dynamic spectrum sharing. His outstanding accomplishments have a lasting impact on both academia in the communications field, due to highly-cited publications, and the wireless industry, through the licensing and adoption of the cognitive radio technology.
His nomination for promotion to IEEE Fellow took into consideration his following contributions:

1. Dr. Liang pioneered the study of joint design of spectrum sensing and spectrum access, which answers the most fundamental question related to cognitive radio design, i.e., how much time is needed for spectrum sensing? The study has been widely adopted by the community to design the sensing time and medium access control (MAC) structures for various types of cognitive radio networks.
2. Dr. Liang and his co-authors have developed various proven schemes workable in stringent environments set by Federal Communications Commission (FCC) and IEEE802.22 group. These solutions are vital to the success of dynamic spectrum access technology due to the requirement to primary user protection.
3. Dr. Liang pioneered the study of applying multi-antennas for cognitive radio, which increases the degree of freedom for dynamic spectrum sharing. The use of spatial dimension for spectrum sharing has opened up new research directions for both cognitive radio community and conventional multi-antenna community.
4. In cognitive radio, an important requirement from secondary users is to maintain the quality-of-service when the system switches from one frequency band to another. Dr. Liang’s earlier work introduced a low-complexity scheme to estimate the statistical channel of one frequency band from that of another band for multi-antenna systems, which laid a foundation for fast beamforming design for wireless applications requiring band switching, including cognitive radio systems.
5. Dr Liang is a worldwide top expert in cognitive radio. This is evident by his profound role in major international cognitive radio conferences, his frequent talks/speeches in international conferences and leading universities worldwide, as well as his large number of publications in prestigious international journals and conferences. His significant contributions to Singapore’s development has also been well recognized in his 2007 IES (Institute of Engineers Singapore) Prestigious Engineering Achievement Award for his work on Cognitive Radio for IEEE Standards on Wireless Regional Area Networks.
