Grant: Discovery Grants Program - Individual

With the*development of 5G mobile access networks, which is an initial network for*communications, big data, internet of things and artificial intelligence (AI),*5G+/6G is being proposed for enhancing the functionalities of 5G, i.e. 5G+/6G*is a global network for connecting anything in the world with low latency and*high speed. To realize 5G+/6G networks, fronthaul communication systems, which*are used to connect centralized baseband units (BBU) with numerous remote radio*heads (RRH) using optical fiber, are the key challenging part of access*networks because the current digital optical fiber communication systems, which*have high complexity, and high power-consumption, cannot be straightforwardly used.*The future fronthaul communication systems must have the features: simple*structure, low complexity, low power consumption, low latency, and supporting*Tb/s transmission. ******This 5-year*Discovery program is responding to the above strategic and global vision to*explore and create future photonics defined radio for 5G+/6G wireless. The*applicant with his research group is poised to conduct fundamental and*innovative researches to achieve cost-effective 5G+/6G fronthaul transmission*technologies with related devices and circuits, which will be the key technologies*of 5G+/6G access networks. The main research goal for this 5-year Discovery is*to propose, study, and explore highly original technologies that are used for*5G+/6G wireless access. Specifically, this research is concerned with the*following concepts, modeling, design and demonstrations: (1) Enabling*technologies for 5G+/6G photonic and mm-wave/THz integrated*circuits/transceivers; and (2) new cost-effective fronthaul transmission*technologies. In (1), InP quantum dot laser modeling that is used for coherent*optical frequency comb generators, and photonic-wireless transceiver design*using coherent optical frequency comb generator are included. In (2), cost-effective*Tb/s fronthaul transmission technologies, such as radio over fiber,*linearization, and spatial division multiplexing etc. will be studied. ******In a long*term, photonics defined radio will lead to many disruptive ICT technologies.*This 5-year Discovery program will sustain Canadian ICT leadership and promote*Canadian economy and human life.
