Fast-Than-Nyquist (FTN) transmission is a promising method to improve the\nspectrum efficiency for future wireless communication systems. However, this\nbenefit of FTN is at the price of inducing the inter-symbol interference (ISI),\nwhich increases the complexity of the receiver. In this paper, a circulated\nblock transmission scheme for FTN signaling, i.e. CB-FTN system is proposed.\nThe detail implementation structure of CB-FTN transceiver is presented,\nin which the ISI caused by FTN transmission is canceled by the frequency-\ndomain equalization (FDE), and the inter-block interference (IBI)\ncaused by the multi-path channel is overcome by the cyclic-prefix. The postprocessing\nsignal to noise ratio (pSNR) is analyzed for the CB-FTN receiver\nwith zero-forcing FDE in AWGN channel, which is verified by the simulation\nresults. Moreover, the BER performances and computational complexity of\nCB-FTN system are compared with the existed scheme.
