Abstract :
This paper deals with noncoherent recognition of modulation types. The main goal is to discriminate a multi-carrier OFDM modulation type from some single-carrier analog and digital modulation types. The proposed solution uses statistics of the received signal, which is observed on the signal amplitude at the output of the intermediate-frequency stage. Not only AWGN noise is used to verify the properties of the recognizer, but also presence of the multi-path propagation.
