ISAC system design for 6G
Book RFI (RF Imaging), Chapters 33-34
Connects the ISAC information theory here to the physical sensing model (wave propagation, resolution limits, CRB analysis) and the practical system design for integrated radar-communication.
Massive MIMO and user scheduling
Book MIMO (Massive MIMO chapters)
With $n_t \to \infty$, the multiuser diversity gain combines with the channel hardening effect. The scheduling problem simplifies dramatically in massive MIMO.
