Abstract:

Aiming at the problem of low accuracy of communication signal recognition and difficult training of network in few-shot learning, a modulation recognition algorithm based on the residual generative adversarial network is proposed. Firstly, this algorithm designs a new residual block unit using Leakyrelu as the activation function of the hidden layer, which can also calculate the gradient for the negative input data. Then, the residual network composed of the new residual units and the convolutional neural network are used as the basic network structure of this proposed algorithm. Moreover, we apply the asymmetric small convolutional kernel with a convolutional step of 1 to better extract the edge feature information of the signal. Finally, Dropout is adopted to replace the pooling operation, and Adam gradient optimization algorithm is selected to complete the network training in an alternate iteration mode. Experimental results show that under the condition of a few-shot learning, the recognition accuracy of the residual generation adversarial network algorithm for 10 modulated signals can reach 91% when the signal to noise ratio (SNR) is higher than 0 dB, which verifies the effectiveness of the proposed method.
