Hi! This is Wireless Frontier Lab (Chinese name: 无线前沿实验室), one of the research labs at College of ISEE@ZJU (since 2023), led by Prof. Lei Liu. Our research focuses on wireless communication and signal procssing, information theory, coding theory, message passing algorithms and beyond. including OAMP/MAMP algorithms, Advanced Random Modulation/Multiplexing, and AI-RAN signal processing.

We have published multiple papers at top IEEE Journals such as TIT, TWC, TSP, TCOMM, and JASC. Our representitive work including three main aspects: Random Modulation, AMP Algorithms, and Turbo Algorithms.
