论文摘要
在本三部分教程的第一部分中审查了正交时间频率空间（OTF）调制的基本概念和挑战。在第二部分中，我们概述了OTFS系统的最新收发器设计，特别关注环状前缀（CP）设计，窗口设计，脉冲塑形，通道估计和信号检测。此外，我们分析了OTFS调制的性能，包括多样性增益和可实现的速率。具体而言，提出了比较模拟，以评估不同OTF检测方案的误差性能，并研究了编码OTFS系统比编码正交频率分割多路复用（OFDM）系统的优势。
The fundamental concepts and challenges of orthogonal time frequency space (OTFS) modulation have been reviewed in Part I of this three-part tutorial. In this second part, we provide an overview of the state-of-the-art transceiver designs for OTFS systems, with a particular focus on the cyclic prefix (CP) design, window design, pulse shaping, channel estimation, and signal detection. Furthermore, we analyze the performance of OTFS modulation, including the diversity gain and the achievable rate. Specifically, comparative simulations are presented to evaluate the error performance of different OTFS detection schemes, and the advantages of coded OTFS systems over coded orthogonal frequency-division multiplexing (OFDM) systems are investigated.
