WebThe first motivation is based on the property that for Gaussian signals only, all cumulant spectra of order greater than two are identically zero. If a non-Gaussian signal is received along with additive Gaussian noise, a transform to a higher-order cumulant domain will eliminate the noise. WebSeveral typical situations unfavorable for second-order direction-finding methods are known to be easily overcome by means of higher-order techniques. In turn, in typical situations unfavorable for higher-order methods, second-order algorithms often perform quite well.
