摘要

5G预计将改善主要关键性能指标(kpi)，如峰值数据速率、频谱效率、功耗、复杂性、连接密度、延迟和移动性。本章旨在全面介绍正在进行的5G波形讨论，并概述主要候选波形。它提供了波形的简要描述，揭示了5G用例和波形设计要求。本章介绍了部署在4G LTE系统中的循环前缀正交频分复用(CP-OFDM)的主要特点。CP-OFDM是5G波形讨论的基准，因为通常会与新波形的性能进行比较。本章考察了主要候选波形的基本特征以及相关的优点和缺点。总结和比较了不同波形的主要特征。

Waveform Design for 5G and Beyond

5G is envisioned to improve major key performance indicators (KPIs), such as peak data rate, spectral efficiency, power consumption, complexity, connection density, latency, and mobility. This chapter aims to provide a complete picture of the ongoing 5G waveform discussions and overviews the major candidates. It provides a brief description of the waveform and reveals the 5G use cases and waveform design requirements. The chapter presents the main features of cyclic prefix-orthogonal frequency-division multiplexing (CP-OFDM) that is deployed in 4G LTE systems. CP-OFDM is the baseline of the 5G waveform discussions since the performance of a new waveform is usually compared with it. The chapter examines the essential characteristics of the major waveform candidates along with the related advantages and disadvantages. It summarizes and compares the key features of different waveforms.
