多天线毫米波通信即将成为主流商业部署。在不久的5G供电的未来，我们预计一个动态的，拥挤的和干扰有限的毫米波信道，这将要求我们利用毫米波天线阵列提供的大范围空间分集。在前几代蜂窝中，通信和联网算法的开发受到基于软件定义无线电的实验的显著帮助。同样，我们认为，这个新时代的挑战将需要开发基于实验的算法，使用软件定义的毫米波多天线系统。在这次演讲中，我们将介绍一个便携式，用户友好，但功能强大，高度可重构的软件定义相控阵收发器平台，用于5G时代的实验和算法开发。该平台具有128个独立的相位和增益控制元件，为64个双极化天线供电，并支持28 GHz的双极化发射和接收。每个元件的相位和增益都可以控制，最多支持8个同步光束。关键电路和天线技术创新实现了免校准操作。此外，所有通信和相控阵波束配置功能都由单个基于Python的API控制，从而允许从简单的软件接口进行完全波束成形控制以及其他软件定义的无线电通信参数。介绍了使用软件定义相控阵的初始5G相关实验。
Multi-antenna millimeter wave communications is on the verge of mainstream commercial deployment. In a not-too-distant 5G-powered future, we expect a dynamic, congested and interference-limited millimeter wave channel that will require us to exploit the large range of spatial diversity afforded by millimeter wave antenna arrays. In prior cellular generations, the development of communications and networking algorithms was significantly aided by software defined radio based experimentation. Similarly, we believe that the challenges of this new era will require the development of algorithms based on experimentation using software defined millimeter wave multi-antenna systems. In this talk, we will present a portable, user-friendly and yet, extremely capable and highly reconfigurable software-defined phased array transceiver platform for experimentation and algorithms development in the 5G era. The platform features 128 independent phase and gain control elements feeding 64 dual-polarized antennas, and supports dual-polarized transmit and receive at 28 GHz. Phase and gain of each element can be controlled, with support for up to 8 simultaneous beams. Key circuit and antenna technology innovations enable calibration-free operation. Moreover, all communications and phased array beam configuration functions are controlled from a single python-based API thereby allowing full beamforming control alongside other software defined radio communications parameters from a simple software interface. Initial 5G related experiments using the software defined phased array is presented.
