Abstract :
In this paper we develop an algorithm based on higher-order cyclic cumulants for the automatic recognition of QAM signals. The method is robust to the presence of carrier phase and frequency offsets. Theoretical arguments are verified with simulations performed for 4-QAM and 16-QAM signals.
