Abstract

This chapter delves into the analysis of Orthogonal Time Frequency Space (OTFS) modulation in a baseband environment, focusing on its superior performance in high-mobility and time-varying channels compared to OFDM. The study investigates the properties of OTFS, such as invariability, separability, and bi-orthogonality, which enable it to extract full channel diversity. The chapter also explores the design and features of OTFS, including its spectral efficiency and mathematical model. A key highlight is the analysis of the Message Passing algorithm for OTFS symbol detection, which offers a low-complexity solution for improving data rate and reducing interference. Simulation results demonstrate the error performance of OTFS under various channel conditions, showcasing its advantages over traditional multicarrier schemes. Additionally, the chapter discusses the effects of damping factors and channel taps on system performance, providing valuable insights into the optimization of OTFS systems.
