Turbo-coded single-carrier faster-than-Nyquist transmission

Abstract

Faster than Nyquist (FTN) transmission is investigated for a point-to-point AWGN link. The FTN is interpreted as a form of coding at the pulse shape level, and accordingly, the so-called Mazo phenomenon is interpreted as a coding gain. Then, it is shown by simulation that such a gain can disappear in a coded FTN transmission with a powerful FEC code, such as turbo code. This result undermines the FTN transmission as an effective technique in an actual communication system.
