  • Automatic modulation recognition is an important research area for the receiver design in the non-cooperative communication system. A digital modulation recognition algorithm is proposed in this paper for the engineering application. Contrast to other algorithm, this one is very simple to be calculated on-line and it also has a good recognition rate in the low SNR environment, furthermore the effect of symbol shape to the parameter extraction has been considered, which can satisfy the need of engineering.
