Practical 5G NR beamforming, CSI and RF optimization — from antenna arrays and the channel matrix all the way to AI-driven beam management. The book I wish I'd had on the cabinet floor.
One-time purchase • Instant access • Lifetime updates
Twelve parts that take you from the physics of the channel to the AI that points the beam — every figure followed by a plain-language "how to read this picture".
Every equation explained in plain words first — channel matrices, SVD, capacity, precoding weights — then the formula, then a worked number.
Elements, ports, panels, array gain, 2D/3D beamforming and the AAU geometry that decides what your cell can actually do.
NR physical layer, reference signals, antenna ports and layers — mapped to TS 38.211/212/213/214 the way RAN1 defines them.
Analog, digital and hybrid beamforming; precoding and beam weights; what each costs in silicon and what each buys in throughput.
CSI framework, CSI-RS configuration and Type I / Type II codebooks — the feedback chain that drives rank and MCS.
The full life cycle: SSB sweep, PRACH association, CSI-RS refinement, TCI/QCL beam indication and recovery.
Rank, MU pairing, beam alignment, cell-edge — real counter chains and the field cases behind low-rank and stalled MU-MIMO.
RIC-driven beam optimization, ML beam prediction, private-5G massive MIMO and where MIMO goes in 6G.
The front matter and the first three chapters are open — including the MIMO maths chapter. No signup required.
45 chapters across 12 parts.
One-time purchase. Instant access in the online reader. Lifetime updates as the beam-management framework evolves.

45 chapters across 12 parts: wireless MIMO foundations and the maths, antenna arrays and beam patterns, the full 5G NR physical layer for MIMO, analog/digital/hybrid beamforming and precoding, the CSI framework with Type I/II codebooks, the complete NR beam-management life cycle, uplink/SRS and reciprocity, mobility and beam-failure recovery, a KPI & troubleshooting part with real field cases, and an advanced part on O-RAN/RIC, AI/ML beam prediction, private 5G and 6G.
Yes. The book is spec-cited end to end against TS 38.211/212/213/214 (PHY, coding, control & data procedures), TS 38.331 (RRC: CSI-RS, SRS, BWP), TS 38.321 (MAC beam indication), TS 38.300/104/101 and the TR 38.901 channel model, with the LTE 36-series mapped alongside.
Yes — the front matter and Chapters 1–3 are an open preview at /massive-mimo-book/reader.html. You can read the foundations and the MIMO maths chapter free before you decide.
Instantly. After payment via Razorpay (UPI, cards, net-banking and international cards) the full book unlocks immediately in the online reader. Lifetime access, no subscription.
Yes — lifetime updates. As 3GPP evolves the beam-management and codebook framework and as massive MIMO deployment practice changes, the book is updated and you get the new content free.
