Abstract: To identify personality of a radio signal, a new method of multi-object optimization is proposed to solve a system of high order cumulants equations. The power amplifier model is first shown to be equivalent to a multi-input single-output system. A system of equations is derived from the cumulant relation between input and output. The system is solved with multi-object genetic optimization to obtain the features. The system of equations is verified by simulation, and the results of estimation are compared with computed values, showing that the proposed method can extract features from the received signal only with minor errors.
