下一代无线系统（即5G）的研究和开发近年来经历了爆炸性增长。在物理层，大规模多输入多输出（MIMO）技术和使用高GHz频段是两个有前途的趋势。毫米波（mmWave）频段，如28、38、64和71 GHz，以前被认为不适合商用蜂窝网络，将在5G中发挥重要作用。目前，大多数5G研究涉及调制和编码方案的算法和实现，新的空间信号处理技术，新的频谱机会，信道建模，5G概念系统验证以及其他系统级使能技术。在本文中，我们首先研究了当代无线用户设备（UE）硬件设计，并揭示了电路和系统上的关键5G UE硬件设计约束。在上述研究和设计权衡分析的基础上，提出了一种用于5G蜂窝用户设备的新的、高度可重构的系统架构，即基于分布式相控阵的MIMO（DPA-MIMO）。最后，链路预算计算和数据吞吐量的数值结果提出的建议架构的评估。
Research and development on the next generation wireless systems, namely 5G, has experienced explosive growth in recent years. In the physical layer, the massive multiple-input-multiple-output (MIMO) technique and the use of high GHz frequency bands are two promising trends for adoption. Millimeter-wave (mmWave) bands, such as 28, 38, 64, and 71 GHz, which were previously considered not suitable for commercial cellular networks, will play an important role in 5G. Currently, most 5G research deals with the algorithms and implementations of modulation and coding schemes, new spatial signal processing technologies, new spectrum opportunities, channel modeling, 5G proof of concept systems, and other system-level enabling technologies. In this paper, we first investigate the contemporary wireless user equipment (UE) hardware design, and unveil the critical 5G UE hardware design constraints on circuits and systems. On top of the said investigation and design tradeoff analysis, a new, highly reconfigurable system architecture for 5G cellular user equipment, namely distributed phased arrays based MIMO (DPA-MIMO) is proposed. Finally, the link budget calculation and data throughput numerical results are presented for the evaluation of the proposed architecture.
