Heterogeneous Transformer: A Scale Adaptable Neural Network Architecture for Device Activity Detection
Yang Li, Zhilin Chen, Yunqi Wang +2
To support the modern machine-type communications, a crucial task during the random access phase is device activity detection, which is to detect the active devices from a large nu…
