The filtered orthogonal frequency division multiplexing (F‐OFDM) system has been recommended as a waveform candidate for fifth‐generation (5G) communications. The suppression of out‐of‐band emission (OOBE) and asynchronous transmission are the distinctive features of the filtering‐based waveform frameworks. Meanwhile, the high peak‐to‐average power ratio (PAPR) is still a challenge for the new waveform candidates. Partial transmit sequence (PTS) is an effective technique for mitigating the trend of high PAPR in multicarrier systems. In this study, the PTS technique is employed to reduce the high PAPR value of an F‐OFDM system. Then, this system is compared with the OFDM system. In addition, the other related parameters such as frequency localization, bit error rate (BER), and computational complexity are evaluated and analyzed for both systems with and without PTS. The simulation results indicate that the F‐OFDM based on PTS achieves higher levels of PAPR, BER, and OOBE performances compared with OFDM. Moreover, the BER performance of F‐OFDM is uninfluenced by the use of the PTS technique.

使用PTS为5G通信提高经过滤波的OFDM的PAPR性能

已推荐将滤波正交频分复用（F-OFDM）系统用作第五代（5G）通信的波形候选。带外发射（OOBE）的抑制和异步传输是基于滤波的波形框架的显着特征。同时，高峰值平均功率比（PAPR）仍然是新波形候选的挑战。部分传输序列（PTS）是缓解多载波系统中高PAPR趋势的有效技术。在这项研究中，采用PTS技术来降低F‐OFDM系统的高PAPR值。然后，将该系统与OFDM系统进行比较。此外，其他相关参数，例如频率定位，误码率（BER），对于有和没有PTS的系统，都将评估和分析计算复杂性。仿真结果表明，与OFDM相比，基于PTS的F‐OFDM具有更高的PAPR，BER和OOBE性能。此外，使用PTS技术不会影响F-OFDM的BER性能。
