摘要：

In this paper, we propose a novel orthogonal precoding based on an efficient decomposed precoder on the real-domain for a successive N-continuous scheme to suppress sidelobes in OFDM systems. Novel theoretical analyses justify its performance, which parallel to that of related precoding schemes. In conclusion, the proposed scheme remarkably reduces the conventional precoding's complexity to a level matching that of FFT for OFDM use through its application of 2.8 % storage overhead while keeping all its inherent advantages such as fast decay of band-edges, and ideal error rate.
