商品描述
This book presents an integrated study of metamaterial-based large-scale antenna arrays and beamforming optimization for both Half-Duplex (HD) and Full-Duplex (FD) massive MIMO (mMIMO) systems. As a cornerstone of future wireless communications, mMIMO provides substantial improvements in capacity and spectral efficiency, which this book illustrates. With strategically designed beamforming, these arrays can precisely direct energy toward intended users, while effectively suppressing interference. Metamaterial structures with tunable electromagnetic properties further enhance performance by enabling compact, high-isolation antenna elements and novel interference mitigation strategies. In addition, hybrid beamforming architectures are investigated to achieve an optimal balance between system performance and hardware complexity. The first part of this book focuses on HD MU-mMIMO. Various planar and non-planar array structures are studied through full-wave simulations and prototype measurements, considering user distributions and hardware non-idealities. Novel nulling beamforming algorithms are developed, targeting both Far-Field angular separation and Near-Field spatially separated users. Deep, precisely aligned nulls are created to effectively suppress multi-user interference to noise levels, while preserving desired signal strength. The second part addresses FD mMIMO, where concurrent transmission and reception promise doubled spectral efficiency, but demand strong self-interference (SI) suppression. A multi-stage transmit-receive isolation framework is introduced, integrating antenna isolation, joint beamforming, and metamaterial absorber structures. By combining beam-level isolation with cancellation techniques, experimental measurements demonstrate that residual SI can be suppressed to the noise floor, thereby ensuring reliable FD mMIMO performance. This book is intended for researchers, engineers and advanced-level students focused on advanced wireless systems, antenna innovations, and 5G-and-beyond technology development. It is especially valuable to R&D professionals in telecommunications companies, RF/microwave design firms, or labs working on next-generation wireless networks, antennas, and full-duplex solutions. The content provides both theoretical foundations and practical design considerations for mMIMO, full-duplex architectures, and metamaterial-based antennas. It also caters to specialists in electrical engineering, wireless communications, antenna/RF design, or signal processing who seek an in-depth exploration of cutting-edge multi-antenna technologies.

本書呈現了一個整合性的研究，探討基於超材料的超大型天線陣列及其在半雙工（Half-Duplex, HD）和全雙工（Full-Duplex, FD）大規模多輸入多輸出（massive MIMO, mMIMO）系統中的波束成形優化。作為未來無線通信的基石，mMIMO 提供了在容量和頻譜效率上的顯著提升，本書對此進行了詳細說明。透過策略性設計的波束成形，這些天線陣列能夠精確地將能量指向目標用戶，同時有效抑制干擾。具有可調電磁特性的超材料結構進一步提升了性能，使得緊湊、高隔離的天線元件和新穎的干擾緩解策略成為可能。此外，本書還探討了混合波束成形架構，以實現系統性能與硬體複雜性之間的最佳平衡。
本書的第一部分專注於 HD 多用戶 mMIMO。通過全波模擬和原型測量，研究了各種平面和非平面陣列結構，考慮了用戶分佈和硬體非理想性。開發了新穎的零點波束成形演算法，針對遠場角度分離和近場空間分離的用戶。創建了深且精確對齊的零點，以有效抑制多用戶干擾至噪聲水平，同時保持所需的信號強度。第二部分則針對 FD mMIMO，並探討了同時傳輸和接收所帶來的頻譜效率翻倍的潛力，但這需要強大的自我干擾（self-interference, SI）抑制。引入了一個多階段的發射-接收隔離框架，整合了天線隔離、聯合波束成形和超材料吸收結構。通過將波束級隔離與消除技術相結合，實驗測量顯示殘餘的 SI 可以被抑制至噪聲底線，從而確保可靠的 FD mMIMO 性能。
本書旨在為專注於先進無線系統、天線創新及 5G 及後續技術開發的研究人員、工程師和高級學生提供參考。對於在電信公司、射頻/微波設計公司或專注於下一代無線網絡、天線和全雙工解決方案的實驗室工作的研發專業人員尤其有價值。內容提供了 mMIMO、全雙工架構和基於超材料的天線的理論基礎和實際設計考量。它也適合於電機工程、無線通信、天線/射頻設計或信號處理領域的專家，尋求對尖端多天線技術的深入探索。
