Comprehensive treatment of multiple access techniques, including FDMA, TDMA, CDMA, and OFDMA, with emphasis on practical system design. Chapter 14 covers multi-user capacity and multiple access, while Chapter 13 discusses CDMA in detail.

A widely used textbook covering the physical layer aspects of cellular systems, including detailed descriptions of FDMA, TDMA, and CDMA as deployed in 1G through 5G. Provides practical link budgets, propagation models, and system design examples relevant to the near-far analysis in Section 19.3.
- N. Abramson, The ALOHA System — Another Alternative for Computer Communications, Proceedings of the Fall Joint Computer Conference, AFIPS, 1970
The seminal paper introducing the ALOHA protocol for random access wireless communication. Abramson's work at the University of Hawaii laid the foundation for all subsequent random access protocols, from Ethernet to Wi-Fi to LTE's random access channel. The throughput analysis ($S = Ge^{-2G}$) remains a cornerstone of networking theory.
- S. Verdu, Multiuser Detection, Cambridge University Press, 1998
The definitive monograph on multi-user detection for CDMA systems. Covers the matched filter, decorrelator, MMSE detector, successive interference cancellation, and the optimal (ML) multiuser detector. The large-system analysis (Chapter 6) establishes the capacity of random-code CDMA in the limit $K, N \to \infty$, directly relevant to Section 19.3.

The paper that reignited interest in NOMA for 5G. Saito et al. demonstrated that power-domain NOMA with SIC provides significant throughput gains over OFDMA in LTE-Advanced scenarios, particularly for cell-edge users. This work stimulated an enormous body of research on NOMA variants and their integration into 5G NR.

The standard reference for information-theoretic capacity of multi-user channels. Chapter 15 covers the MAC capacity region, superposition coding, and the polymatroidal structure of the capacity region. Essential background for the NOMA analysis in Section 19.2.
- L. G. Roberts, ALOHA Packet System With and Without Slots and Capture, ACM SIGCOMM Computer Communication Review, 1975
Extended Abramson's ALOHA analysis to include slotted operation and capture effects. Roberts showed that synchronising transmissions to slot boundaries doubles the throughput from $1/(2e)$ to $1/e$, and that the capture effect in fading channels can further improve performance.
- K. Fengler, P. Jung, and G. Caire, SPARCs for Unsourced Random Access, 2021
Develops a coded compressed sensing framework for unsourced random access using sparse regression codes (SPARCs) with AMP decoding. Achieves near-optimal energy-per-bit efficiency for massive random access with hundreds of active users, providing the theoretical foundation for grant-free access in 5G mMTC and beyond.
- E. Bjornson, E. G. Larsson, and T. L. Marzetta, Massive MIMO: Ten Myths and One Critical Question, IEEE Communications Magazine, 2016
Addresses common misconceptions about massive MIMO, including the FDD vs. TDD debate. The paper clearly explains why TDD with channel reciprocity is essential for massive MIMO and debunks the myth that FDD massive MIMO is feasible with compressed feedback. Directly relevant to the duplexing analysis in Section 19.5.
