Research & Innovation
The fundamental goal of Professor Wang’s research is to develop new wireless communications technologies for better supporting the emerging needs from people, industry and hyper-connected society. By integrating theoretical exploration, engineering design as well as intelligent operation of advanced wireless systems and networks, the main technical objective of his research is to achieve to efficient, secure and reliable exchange of signals, data and knowledge among distributed wireless and Internet-of-Things (IoT) systems.
As a passionate innovator, Professor Wang has created many highly original concepts and engineering solutions by overcoming the most critical and complex issues of wireless communications, communication security, and industry IoT systems. He holds 30 granted and pending patents, with over 20 of them as the first and sole inventor. Recent inventions include end-to-end latency reduction and distributed network synchronization, multi-attributes enabled device/user authentication, and a multi-functional integrated wireless network for indoor locationing, tracking and communications.
Professor Wang and his research group are currently working on the following technical areas:
- 5G and beyond/6G technologies, particularly on intelligent utilization of radio-resources in time, frequency and space domains through opportunistic, non-orthogonal and situation-aware use of communications resources in OFDM/MIMO/NOMA systems.
- Multi-Dimensional Resource Utilization
- Diverse QoS Provisioning & Network Slicing
- Intelligent Operation of NOMA/Massive MIMO Systems
- Power and Spectrum Efficient 5G/6G Communications
- Cooperative Communications and Networking

My Research Group
Dr. Wang currently supervises over 20 researchers at Western, manages more than 10 research projects and leads the Innovation Centre for Information Engineering and Laboratory for Emerging Communications Systems, which is supported by Canada Foundation for Innovation (CFI).
One current research theme in the group is the development of dynamic transmission technologies to support smooth ubiquitous communications in the presence of dynamic electromagnetic interference, network traffic and user demand conditions. Dr. Wang and six researchers under his supervision have developed several responsive transmission techniques, which follow-up with real-time variations.
Another aspect of Dr. Wang’s current research program is spectrum and battery power efficiency, and improved mobile communications. Traditional wireless systems are often designed statically, which leads to extremely low spectrum and battery power efficiency. Channel prediction-based power control, location-based network management and spectrum-efficient transmission schemes have been developed to address the difficulties associated with traditional communications systems. Several DSP/FPGA prototypes have been developed to verify these technologies, and several industrial partners have been engaged for commercialization purposes.
