The IDLab Ghent research group is seeking a highly motivated and talented PhD student to join the Software-Defined Radio (SDR) research team. Digital communication plays a pivotal role in professional environments, supporting both persons, machines to interact with each other over a communication network. In professional environments, such as industry automation (industry 4.0), communication becomes increasingly diverse, and demands more reliable and time-critical end-to-end wireless connectivity, that can seamlessly adapt to dynamic environments and application needs. What is also lacking in today’s wireless network is uniform coverage, users often rely on connection to a specific access point, and performance varies when moving around. The next generation Wi-Fi needs to support distributed and coordinated AP architectures, whereby multiple APs can simultaneously serve a single user with coherent beamforming. In short, we want to advance wireless communications to the next level on these aspects: uniform coverage, end-to-end latency, time synchronization accuracy among distributed applications across diverse network segments, reliability/QoS for high-priority and safety-critical traffic. Today, we are far from achieving that vision, as most research is limited to theoretical or simulation studies, ignoring real-world impairments. Individual access points produced by different vendors rarely cooperate, features such as coherent beamforming among different access points have great potential but cannot be realized in real-life.
In recent years, software-defined radio becomes a popular tool in research community, the SDR team of UGent has created the full stack open-source Wi-Fi chip design openwifi (https://github.com/open-sdr/openwifi). Many innovations has been built above openwifi, such as support of synchronization and Time Sensitive Network (TSN), MIMO diversity, for a complete list of publications using openwifi please refer to (https://github.com/open-sdr/openwifi/blob/master/doc/publications.md).
This PhD vacancy targets to use openwifi to deliver solutions of the advanced WiFi chip for professional end-to-end communication networks that stand out in fulfilling, guaranteeing the challenging requirements of ultra-reliable and time-and-safety-critical applications running on top.
We offer the opportunity to do this research in an international and stimulating environment. The IDLab research group belongs to both Ghent university and IMEC. Ghent University consistently ranks among the best 100 universities in the world. And IMEC is world’s leading independent R&D research hub. Our research center is located in the heart of Europe, Ghent is a beautiful and welcoming city (https://www.lonelyplanet.com/articles/ghent-belgiums-best-kept-secret) with plenty of cultural and leisure activities.
The selected candidate will be offered a 4-year employment, with an intermediate evaluation after the first year (1+3 years). The salary is competitive and will be determined by the university salary scales. In addition, staff members can count on a number of benefits, such as a broad range of training and educational opportunities, 36 days of vacation leave, bicycle allowance, and more.
In general, under the supervision of prof. Ingrid Moerman, you will prepare a PhD dissertation on implementation of advanced WiFi chips for professional applications: end-to-end oriented efficient software-hardware co-design towards reliable and low-latency solutions in professional environments. We are seeking a PhD candidate to enhance the next generation wireless chip design upon openwifi, with the following requirements:
You have (or will obtain in the next months) a (European) master's degree in computer science, or electronic engineering, or equivalent. Your degree must be equivalent to 5 years of studies (bachelor + master) in the European Union.
You should have at least one of the two skills below:
Deep understanding of future Wi-Fi standards is a plus, especially the PHY and Low MAC for the new features such as OFDMA, or MU-MIMO, and cell-free massive MIMO and beamforming.
Experience in synchronization standardization, such as Precition Time Protocol (PTP), is a plus. As we foresee to realize tight synchronization among access points to support coordinated multi-AP operation in view of coherent beamforming.
Experience in software-hardware co-design is a plus, as we want to achieve true real-time control of parameters in MIMO and beamforming for optimal network performance.
Experience in experimentation is a plus, we foresee to use openwifi for scale end-to-end proof-of-concept validation in the field.
During the PhD study, you will likely carry out some of the following tasks:
Send your application by email to Prof. Ingrid.Moerman (Ingrid.moerman@ugent.be), dr. Xianjun Jiao (xianjun.jiao@ugent.be) and dr. Wei Liu (wei.liu@ugent.be). Applications should include
After a first screening, selected candidates will be invited for an interview (also possible via Teams).
Application deadline: continuous evaluation until the vacancy is filled.
