This paper propose the theoretical analysis of the DFT based overlapped frequency division multiplexing (OvFDM)/non-orthogonal frequency division multiplexing(NOFDM) communication system, and investigates the impact of conventional cyclic-prefix and zero-padding cyclic-prefix respectively for the OvFDM-DFT system in the time-variant frequency-selective(More)
This paper proposes a time and frequency synchronization technique for MIMO OFDM system by employing the loosely synchronous (LS) codes as the training sequences. The auto-correlation functions of all LS codes are ideal, and there exists an interference-free window (IFW) or a zero correlation zone (ZCZ) in their cross-correlation functions of the LS codes(More)
We extend the concept of faster-than-Nyquist (FTN) signaling to linear digital modulation using arbitrary modulation pulses, called generalized faster-than-Nyquist signaling (GFTN). A universal definition of nominal bandwidth is given so that “how fast” can be measured for GFTN like FTN using T-orthogonal pulses. The capacities and their(More)
