| Abstract: | During recent years, the growth of research in higher order spectral estimation technique has been further developed and higher order statistics has found wide application in many diverse fields. In this paper, a brief review of developing history of higher order spectral estimation technique is provided and the advance of methods of bispectrum (third order spectrum) estimation is emphatically presented. |
