Abstract： This paper proposes a lightweight 2D convolution-based adaptive visibility graph network for radio modulationrecognition.ByprocessingIQsignals as 2Dinputs andadaptivelyconstructing graph structures，itsigniicantly reduces computational cost while preserving channel corelation.Experiments show superiorrecognition performance with lower parameters，computations，and memory usage than existing models，achieving anaccuracy-efficiency balance

Keywords： adaptive visibility graph network; modulation recognition; accuracy-efficiency balance
