| Abstract: | Under multipath channels, concerning with the problem of automatic recognition of modulation schemes, an algorithm of automatic modulation recognition (AMR) based on transform domains has been proposed. Based on the characteristic parameters extracted from transform domains, the automatic modulation recognition has been realized by employing decision theory. Analytical and simulation results show that the algorithm achieves better performance than other similar algorithms due to its higher recognition accuracy and more robust property. |
