摘要

正交预编码(OP)是减少正交频分复用(OFDM)信号带外发射(OOBE)的一种前置方案。它可以在期望的频率上形成具有深凹痕的频谱，而频率之外的OOBE没有得到充分的降低。为了改进传统的OP，本文提出了一种混合的OOBE减少方法。数值实验结果表明，该方法能有效地降低超弦脱弦率。

Hybrid Method for Out-of-Band Emission Reduction of OFDM Signal

Orthogonal precoding (OP) is a preceding scheme for the out-of-band emission (OOBE) reduction of orthogonal frequency division multiplexing (OFDM) signals. It can shape a spectrum with deep notches at desired frequencies, while OOBE outside the frequencies are not reduced sufficiently. To improve the conventional OP, this paper proposes a hybrid method for OOBE reduction. Numerical experiments show that the proposed method can sufficiently reduce the OOBE.
