Abstract

Orthogonal Frequency Division Multiplexing(OFDM) systems suffer from large out-of-band emission(OOBE). As one of the approaches to suppress the OOBE, the precoding technique is able to achieve significant OOBE suppression with a small spectral efficiency loss and does not depend on the input data. In this paper, a low-complexity individual precoded OFDM (I-P-OFDM) by precoding each contiguous frequency band independently is presented. Furthermore, two resource block (RB) based precoding schemes, namely, the U-RB-P-OFDM and NU-RB-P-OFDM are presented. The RB structures utilized in these two schemes enables mitigation of the precoding matrix dependency on the spectrum allocation. Numerical results show that all three schemes can achieve satisfying spectrum containment without any degradation in BER performance, and provide various tradeoffs between spectral efficiency, computational complexity, and PAPR performance.
