“…It has been observed that the employing of equalizer cannot improve the bit error rate performance at τ = 0.9. Note that this observation is identical to the result given in [15]. So, if τ ≥ 0.9, it can be stated that there is no benefit of using equalizer in LDPC coded FTN system.…”

“…Thus, FTN system with channel coding is needed to ensure reliable transmission over noisy channels [7], [11]. The idea of applying FTN signaling with the powerful channel codes called low-density parity-check (LDPC) codes has been studied by many researchers [5], [12]- [15]. Recently, it is found that LDPC coded FTN system is very robust to both ISI and noise since this combination can achieve good BER performance without utilizing ISI equalizer [16].…”

Faster-than Nyquist (FTN) signaling is a research topic that has been drawing increased attention due to its capability of improving transmission speed without the need of extra bandwidth. However, the deployment of FTN signaling introduces inter-symbol interference (ISI) which severely degrade system performance. Interestingly, even without ISI equalizer, it has been recently shown that the joint application of LDPC codes with FTN signaling can exhibit rather good performance. To further improve the performance of LDPC codes over FTN systems, a transmission scheme that utilizes uniform shortening LDPC codes is proposed in this paper. It was found that their shortening counterpart can provide a coding gain at least 0.4 dB over a wide range of FTN factors compared with FTN systems that employ conventional LDPC codes. Moreover, using LDPC coded ISI-free system as the benchmark, the proposed transmission scheme can possibly provide 43% improvement in data rate with rather small performance degradation.INDEX TERMS Faster-than-Nyquist signaling, LDPC codes, coded FTN systems, shortening.

The Korean Institute of Communications and Information Sciences (KICS), which is the largest information and communication technology institute in Korea, has been active in working towards development and standardization of mobile communication technology. In response to the need to meet upcoming 6G technical challenges in innovative applications such as hologram telepresence, extended reality (XR), digital twin, and connected robotics, the KICS 6G research initiative (KICS 6GRI) group has been created to establish a vision for key 6G technologies and identify research trends and directions. This article, therefore, covers major performance indicators and requirements envisioned by the KICS. In addition, we provide a comprehensive discussion of various candidate 6G technologies including (sub-)terahertz (THz), intelligent reflecting surface (IRS), artificial intelligence (AI)-based techniques, and non-terrestrial network (NTN).Index Terms-6G, the Korean Institute of Communications and Information Sciences (KICS), mobile communication standard.

Faster-than-Nyquist (FTN) signaling is a non-orthogonal transmission technique, which has the potential to provide significant spectral efficiency improvement. This paper studies the capacity of FTN signaling for point-to-point single-input single-output (SISO) and multiple-input multiple-output (MIMO) channels. Although the capacity of SISO FTN was studied previously, due to some incomplete prerequisites, the exact capacity expression was not found. In this paper we resolve these issues for SISO FTN and generalize the result to MIMO FTN. We show that joint waterfilling in time and space is capacity achieving for MIMO FTN.
