| Outline of Final Research Achievements |
We have developed a novel low-complexity soft-decision demodulator for the faster-than-Nyquist (FTN) signaling. More specifically, the proposed demodulator is based on the minimum mean-square error (MMSE)-based frequency-domain equalizer (FDE). Furthermore, in order to improve the achievable error-rate performance of the proposed algorithm, we invoked the low-complexity noise-whitening scheme. The serially-concatenated FTN architecture was proposed, which allows us to attain a good error-rate performance, which is close to that of the conventional Nyquist-based counterpart.
