Project Summary: Faster than Nyquist (FTN) is a promising physical layer technique that has the potential to significantly improve spectral efficiency (bit/s/Hz) in communication systems. In this transmission technique, information carrying pulses are transmitted faster than the Nyquist limit, and this transmission causes inter-symbol interference, which degrades the communication quality. The foundations of the FTN technique date back to the 1960s and 1970s. Mazo showed in 1975 that FTN can achieve the same error performance as Nyquist, provided that the acceleration of pulses does not exceed a certain limit and that inter-symbol interference is eliminated at the receiver. Significant advances have been made in silicon technology and signal processing techniques since 1975. On the other hand, the transmission rates required for future communication networks are very high. These mentioned developments and high-rate requirements make many experts in both academia and industry think that the FTN transmission technique is finally a technology whose time has come.
