The Demodulation of Non-Orthogonal Multiple Modulation Based All Phase

Abstract

Non-orthogonal Multiple Modulation (NOMM ) is different from the traditional modulation and is very efficient. To solve the problems like complicate modulation, huge calculation and low accuracy, All Phase Fast Fourier Transform (APFFT) is presented in this paper. And this method is proved correct in theory. The experiment shows that it is reasonable, and can keep high accuracy even in high noise conditions.
