Recognition of single and multicarrier digital modulations

Single and multicarrier digital modulations have been widely adopted for broadband wireless local and metropolitan networks and long term evolution (LTE) systems. This paper presents a second-order cyclostationarity-based algorithm for the recognition of single and multicarrier digital modulations. The applicability of this method is confirmed using waveforms generated and acquired by laboratory instrumentation and off-the-air signals, as well as computer simulation experiments.
