— This paper describes a modular hardware platform of a multiuser (MU) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) testbed. The hardware platform is based on multiple field programmable gate arrays (FPGAs), provides four integrated radio-frequency (RF) chains, and has capabilities for extension boards. The(More)
Preface Wireless standards are subject to rapid development and frequent changes, making old hardware obsolete at a high rate. On the other hand, the constantly increasing computational power of general purpose computers allows developers to move functionality away from hardware and specialized processors, to high-level software running on arbitrary general(More)
This paper provides an overview of a real-time multi-user multiple-input multiple-output (MIMO) communication testbed designed for demonstration and assessment of real-world wireless communication aspects. The testbed is built on a modular hardware platform consisting of three different boards and incorporates a MIMO-OFDM-based physical (PHY) layer, an(More)
