Main scripts

• GenDataset.m: generates a set of HOS (i.e., HOM and HOC) to identify the modulation type. You can edit the transmitter, channel, and receiver parameters in this file.
• DetectionResults.m: shows the detection performance, i.e., the probability of correct identification in terms of the SNR.

Fonction scripts

• f_HOS_Extraction.m: includes the following processes: source signals generation, channel mixing, blind source separation (BSS), and features extraction.
• f_CalcHOS.m: given a signal x, this function estimates HOC and both denoised and non-denoised HOM.
• f_SCMA.m: is the function that performs the BSS process following the SCMA algorithm.
