A convolutional neural network (CNN) has been successfully applied to in-air handwritten-Chinese-character recognition (IAHCCR). However, the existing models based on CNN for IAHCCR need to convert the coordinate sequence of a character into images. This conversion process increases training and classifying time, and leads to the loss of …

An over-the-air adversary attempts to introduce a perturba-tion waveform, δ(t), to fail the target classifier at the legitimate receiver. However, the adversarial attack to the modulation classifier suffers from the effects of over-the-air transmission, and the received signal at the receiver becomes r δ(t) = h rtx(t)+h raδ(t)+n(t) (3) = r(t)+h
