摘要
A method for determining the signal constellation of a received signal establishes a moment based on each waveform, squares the moment, fourth powers the moment, divides the fourth power by the square to obtain a ratio, and compares the ratio to a threshold. If the ratio is less than threshold, the signal constellation corresponds to a first type, and if greater than the threshold, the signal constellation corresponds to a second type. The method can be generalized to a magnitude mean in place of a second moment.
