Title
LDL-precoded FTN Signaling with Power Allocation in The Block Fading Channel
Abstract
In this paper, to obtain a higher information rate in the block fading channel, we propose an LDL-decomposition-based linear precoded faster-than-Nyquist (FTN) signaling with power allocation. We further propose an LDL-decomposition-based linear precoded FTN signaling with truncated power allocation (LDL-TPA-FTN) to extend the application range of the acceleration factor. Moreover, we derive the corresponding maximum average information rate, outage probability, and outage capacity of the proposed schemes. Also, the complexity of the proposed schemes is analyzed theoretically and compared with classic ones, which shows the proposed schemes have lower complexity. Numerical results show that the proposed schemes have higher outage capacity and achievable rate than Nyquist signaling in the block fading channel. Also, the proposed schemes can reduce the incurred inter-symbol interference (ISI) and have the same application range of the acceleration factors as the singular value decomposition-based FTN. Moreover, a trade-off should be made between the side-lobe suppression of the power spectral density of the transmit signal and threshold selection in LDL-TPA-FTN to obtain higher performance gain for small acceleration factors.
