Abstract

Pi-Radio's vision is to democratize wireless research by providing advanced mmWave Software Defined Radio (SDR) platforms to the community at plainly affordable price points. Pi-Radio's v1 SDR features a 4-channel fully-digital transceiver that operates in the 57-64 GHz band. Fully-digital (a.k.a. MIMO) transceiver architectures enable multiple simultaneous TX/RX beams, standing in stark contrast with phased arrays featuring analog beamformers that are capable of transmitting/receiving only one beam at a time. This opens up a whole set of research problems to work on, across virtually every layer of the protocol stack. In this demo, the team will: (1) prove the correct formation of different TX/RX beams by applying geometrically determined beamforming weights, and (2) prove the benefits of fully-digital beamforming by transmitting four independent streams of data with an OFDM-based physical layer.

使用Pi-Radio毫米波SDR平台的全数字波束形成演示

Pi-Radio的愿景是以可承受的价格向社区提供先进的毫米波软件定义无线电(SDR)平台，从而实现无线研究的民主化。Pi-Radio的v1 SDR具有4通道全数字收发器，工作在57-64 GHz频段。全数字(又名MIMO)收发器架构可同时实现多个TX/RX波束，与具有模拟波束形成器的相控阵形成鲜明对比，后者一次只能发射/接收一个波束。这就开启了一套完整的研究问题，几乎跨越了协议栈的每一层。在这个演示中，该团队将:(1)通过应用几何确定的波束形成权重来证明不同TX/RX波束的正确形成，(2)通过使用基于ofdm的物理层传输四个独立的数据流来证明全数字波束形成的好处。
