A Research on Automatic Modulation Recognition with the Combination of the Rough Sets and Neural Network

摘要

Automatic modulation recognition of modulation signals is the key problem in non-cooperative communication systems. The method which combines the rough set theory and the neural network is designed for identifying the six modulation types based on the research on the feature set of digital modulation recognition. Simulation results show that the new method simplifies the structure of neural networks and decreases the training time without reducing the recognition rate.
