已经针对5G新无线电（NR）物理层研究并提出了几种不同的波形处理技术，以支持新的混合参数集和异步服务。这些不同技术的评估和比较通常基于发射器和接收器单元中的匹配波形处理。在这篇文章中，它表明，不同的技术可以灵活地混合，使之有可能分别优化发射机和接收机实现的复杂性和性能的权衡。通过为发射机和接收机基带处理设置足够的要求，允许透明设计，混合不同的波形处理技术是可能的。我们提供了如何在透明设计的背景下独立应用和评估发射机和接收机单元的基本框架，以及通过无与伦比的发射机和接收机波形处理实现无线电链路性能的大量示例。所讨论的方法和解决方案简化了标准化，改善了透明的发射机和接收机共存，并为5G NR物理层硬件和算法设计的性能改进提供了一条面向未来的演进路径。
Several different waveform processing techniques have been studied and proposed for the 5G new radio (NR) physical layer, to support new mixed numerology and asynchronous services. The evaluation and comparison of these different techniques is commonly based on matched waveform processing in the transmitter and receiver units. In this article, it is shown that different techniques can be flexibly mixed, making it possible to separately optimize complexity-performance trade-offs for transmitter and receiver implementations. Mixing different waveform processing techniques is possible by setting adequate requirements for transmitter and receiver baseband processing allowing transparent design. We provide the basic framework of how transmitter and receiver units can be independently applied and evaluated in the context of transparent design and an extensive set of examples of the achievable radio link performance with unmatched transmitter and receiver waveform processing. The discussed approach and solutions simplify standardization, improve transparent transmitter and receiver coexistence, and enable a futureproof evolution path for performance improvements in 5G NR physical layer hardware and algorithm design.
