Title
Waveform Design of Zero Head DFT Spread Spectral Efficient Frequency Division Multiplexing.
Abstract
Zero head discrete Fourier transform (DFT) spread spectral efficient frequency division multiplexing (ZH-DFT-s-SEEDM) as a non-orthogonal multicarrier transmission scheme is proposed for the bandwidth compressing. A zero head DFT spread approach consists in this waveform design for reducing the peak-average-power-ratio (PAPR) and suppressing the out-of-band emissions introduced by the inter symbol interference and the inter carrier interference. Simultaneously, the corresponding receiver design is given, and a low complexity zero-forcing (ZF) detection algorithm is attached to the ZH-DFT-s-SEEDM receiver design. As the loss of orthogonality, the conventional SEEDM detector is overly complex, and however, the ZF detector as a linear detector performs well in the ZH-DFT-s-SEEDM system by adjusting the length of zero head. Simulation results show that the ZH-DFT-s-SEEDM signal achieves lower out-of-band emissions and a better PAPR performance than the conventional SEEDM signal at the same bandwidth compressing ratio. The binary error ratio (BER) performance of a ZH-DFT-s-SEEDM receiver with a ZF detector is also investigated. It performs better as the longer zero head inserted, and can achieve the better BER performance than conventional SEEDM and OEDM at the low signal-to-noise-ratio (SNR) for a particular number of zero head, and the BER performance of ZH-DFT-s-SEEDM remained the same as OEDM and traditional SEEDM at the high SNR.
