In this chapter, we delve into the transceiver design for semantic communications (SC). Specifically, we first summarize established designs for key components in SC, with a key focus on the knowledge base (KB) and semantic encoders/decoders crucial for single‐user SC. Our discussion then extends to multiuser SC, specifically emphasizing the synergy between various multiple access (MA) schemes and SC, including orthogonal multiple access (OMA), space‐division multiple access (SDMA), non‐orthogonal multiple access (NOMA), rate‐splitting multiple access (RSMA), and model‐division multiple access (MDMA). In the end, we explore various applications of SC and analyze the potential alterations in transceiver design required for these applications.
