论文摘要
对于未来的无线通信技术，强烈期望吞吐量等能力的增加。由于较大的未开发带宽，Sub-Thz带中的传播似乎是满足不断增加的容量需求的潜在解决方案。在这些频率下使用的振荡器会产生相位噪声，从而诱导必须解决的信号中的临界变形。 PN的相关性使得很难克服。如今，考虑到sub-thz频段中传输的5G新无线电的多载波波形扩展的扩展。在本文中，我们引入了一种称为插值过滤器（IF）的新算法，该算法有效地估算并补偿了PN对DFT-S-OFDM系统的影响。具体而言，它基于PN的随机特性的使用，并且与3GPP相跟踪参考信号方案兼容。我们在使用高阶调制时强调了比已知技术的性能改进。
For future wireless communication technologies, an increase in capabilities such as throughput is strongly expected. Transmission in the sub-THz bands (>90 GHz) seems to be the potential solution to meet the ever-increasing capacity demands due to the large unexploited bandwidth. Oscillators used at these frequencies generate phase noise that induces critical distortions in the signal that must be addressed. The correlated nature of PN makes it difficult to overcome. Nowadays, there is a growing interest in considering the extension of multicarrier based waveforms of the 5G new radio for transmissions in the sub-THz bands. In this paper, we introduce a new algorithm called the interpolation filter (IF), which efficiently estimates and compensates PN effects on DFT-s-OFDM systems. Specifically, it is based on the use of stochastic properties of the PN and is compatible with the 3GPP phase tracking reference signal scheme. We highlight a performance improvement over known techniques when using high-order modulation.
