Abstract:

Modulation recognition is the key problem in non-cooperative communication.An analog-digital modulation recognition algorithm based on decision theory is described in this paper.And the parallel application of the algorithm based on CUDA is proposed.The modulation recognition of most of the analog and digital signals is achieved through simulation.The parallel acceleration effect is significant based on CUDA.

Key words: modulation recognition;decision theory;feature extraction;parallel design
