Abstract :
Although the single antenna vector OFDM (V-OFDM) and other similar systems have the advantages of robustness to channel spectral nulls and high spectrum efficiency, its practicability may be degraded by the system high complexity. In this paper, a novel DFT scrambling vector OFDM (DFT-SV-OFDM) scheme is developed. Compared with V-OFDM system, this scheme improves the system PAPR and complexity, and shows a comparable performance as well.
