Abstract

Orthogonal frequency division multiplexing (OFDM) technique, with a broad usage in recent communication technologies, provides a good performance that is mostly appropriate for target quality of service levels. Yet, it will not be effective for future requirements due to its synchronization and spectral efficiency related communication system drawbacks. To address these issues, universal filtered multi-carrier (UFMC) technique has been proposed. Specifically, UFMC's less strict synchronization requirements and its increased spectral efficiency compared to the OFDM render it very desirable for 5G. In this study, UFMC is implemented by using software defined radios in real-time for the first time in the literature. With an effective synchronization solution, UFMC's design issues are tackled and a proper design model that is feasible for 5G requirements is demonstrated. Two methods are proposed for improvement of channel estimation and pilot usage for synchronization process. Moreover, as shown with real-time experiments, by carefully adjusting UFMC parameters, UFMC outperforms OFDM that is implemented in same configuration.

通用滤波多载波系统:5G候选波形的试验台部署

正交频分复用(OFDM)技术是当前通信技术中应用最为广泛的一种技术，它具有非常适合于目标服务质量水平的优良性能。然而，由于其同步和频谱效率相关的通信系统缺陷，它将无法有效地满足未来的需求。为了解决这些问题，提出了通用滤波多载波(UFMC)技术。具体来说，与OFDM相比，UFMC不太严格的同步要求和更高的频谱效率使其非常适合5G。在本研究中，UFMC在文献中首次使用软件定义无线电实时实现。通过有效的同步解决方案，解决了UFMC的设计问题，并展示了适合5G需求的适当设计模型。提出了两种改进同步过程中信道估计和导频利用率的方法。此外，实时实验表明，通过仔细调整UFMC参数，UFMC优于在相同配置下实现的OFDM。
