Abstract:

Specific emitter identification (SEI) plays a crucial role in civilian spectrum management. Traditional deep neural network methods face many challenges in emitter identification, including extended training duration, high energy consumption, and low computational sparsity. To address these issues, a deep spiking complex neural network (S-CNet) model was designed, which integrates pulse neural layers and utilizes the intrinsic properties of complex data to enhance signal representation capabilities, significantly optimizing computational efficiency and reducing hardware resource requirements. The test results have shown that the recognition accuracy of this model reaches 96%, the average inference time for a single piece of data is 0.19 ms, and it is superior to the traditional neural network models in terms of model parameter scale, inference speed, and inference data energy consumption.
