“…Spooner proposed a Minimum Distance (MD) classifier based on Cyclic Cumulants [10] [21] [22] as a solution to the MAMC issue. Thereby, the features used for the classification are chosen by puncturing the two-dimensional n th -order Cyclic Temporal Cumulant Function (CTCF) at some specific frequencies and cyclic-frequencies for different values of n. The method aims at being blind and only requires the knowledge of a few parameters.…”

Abstract-The scarcity of the usable satellite spectrum has led to a need for advanced communication techniques. Among them, multi-satellite networks have been promoted for their ability to reuse the frequency bands in a more aggressive manner. This is made possible by sharing both the spectral and spatial degrees of freedom. Meanwhile, the concept of Cognitive Satellite (CS) was deeply investigated to make the best of these novel architectures. In this context, very few blind signal processing methods were proposed to tackle the co-channel interference issues entailed by such systems. Herein, we develop a novel low-complexity algorithm for blind Automatic Modulation Classification (AMC) and parameters estimation in the strongly interfering scenario. The proposed method rely on an Analytical study of the M thPower nonlinear Transformation (AM PT) of the co-channel mixture. Theoretical analysis and extensive simulations show the effectiveness of the proposed method in various scenarios.

Blind estimation of the transmission parameters of orthogonal frequency division multiplexing (OFDM) signal is an important issue for various civilian and military applications. This paper presents a new cyclostationarity-based approach to blind estimation of OFDM signal parameters. Analytical expression for extracting transmission parameters from second-order cyclic cumulant (CC) of OFDM signal is derived first, with the consideration of the effects of time dispersion and consistent estimator errors on CC. The approach exploits the cyclostationarity of OFDM both in time delay domain and cyclic frequency domain; a statistic hypothesis testing framework was formulated to determine the threshold for detecting the presence of cycles of OFDM signal. The simulation results reveal that the proposed approach is robust for both previous synchronization and channel condition concurrently.
