Multi-carrier FTN sending/receiving method based on FRFT and related equipment

The invention discloses a multi-carrier FTN signal sending/receiving method based on FRFT and related equipment. the sending end sends a multi-carrier FTN signal to a receiving end, and the sending end performs IFRFT conversion on a first parallel symbol sequence formed according to an information source and processes the signal formed by the IFRFT conversion to generate the multi-carrier FTN signal; the receiving end performs FRFT conversion on a second parallel symbol sequence formed according to the multi-carrier FTN signal; and the receiving end performs soft interference deletion on the signal generated after the FRFT transformation according to an interference coefficient, and the interference coefficient is determined based on a transformation coefficient corresponding to the FRFT transformation and an inverse transformation coefficient corresponding to the IFRFT transformation. According to the multi-carrier FTN signal sending method/receiving method based on the FRFT, the sending end/receiving end an
