  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.
