| 为研究正交频分复用(OFDM)系统的带外（OOB）辐射和高峰值平均功率比（PAPR）两个问题，阐述了两个问题的成因和传统技术的优势与不足，介绍了常见的预编码矩阵。根据OFDM系统原理，对OOB辐射和PAPR问题进行建模，构建新的预编码系统模型。最后对传统OFDM、预编码、联合预编码三者进行了比较，并展望了预编码干扰控制需进一步研究的方向。 |

| Abstract: |
| In order to research out-of-band (OOB) radiation and high peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) system,this paper discusses the causes of above two problems and the advantages and disadvantages of traditional technology,and introduces the common precoding matrices. According to the principle of OFDM system, the model of OOB radiation and PAPR is modeled, and a new precoding system model is constructed. Finally, the traditional OFDM, precoding and joint precoding are compared, and the open issues for future research on precoding for interference control are pointed out to promote new research and development in this field. |
| Key words: orthogonal frequency division multiplexing (OFDM) interference control precoding out-of-band (OOB) radiation |
