Quadratic Transform for Fractional Programming in Signal Processing and Machine Learning
Kaiming Shen, Wei Yu
Fractional programming (FP) is a branch of mathematical optimization that deals with the optimization of ratios. It is an invaluable tool for signal processing and machine learning…
Joint Device Selection and Power Control for Wireless Federated Learning
Wei Guo, Ran Li, Chuan Huang +3
This paper studies the joint device selection and power control scheme for wireless federated learning (FL), considering both the downlink and uplink communications between the par…
Energy Efficient HARQ for Ultrareliability via Novel Outage Probability Bound and Geometric Programming
Kaiming Shen, Wei Yu, Xihan Chen +1
Hybrid automatic repeat 1 request (HARQ) is a key enabler for ultrareliable communications. This paper optimizes transmit power for the initial transmission and the subsequent retr…
Stochastic Transceiver Optimization in Multi-Tags Symbiotic Radio Systems
Xihan Chen, Hei Victor Cheng, Kaiming Shen +2
Symbiotic radio (SR) is emerging as a spectrum- and energy-efficient communication paradigm for future passive Internet-of-things (IoT), where some single-antenna backscatter devic…
Joint Annotator-and-Spectrum Allocation in Wireless Networks for Crowd Labelling
Xiaoyang Li, Guangxu Zhu, Kaiming Shen +3
The massive sensing data generated by Internet-of-Things will provide fuel for ubiquitous artificial intelligence (AI), automating the operations of our society ranging from transp…
Power Control for Massive MIMO Systems with Nonorthogonal Pilots
Xihan Chen, Kaiming Shen, Hei Victor Cheng +3
