A real-time experimentation platform for sub-6 GHz and millimeter-wave MIMO systems

Abstract: The performance of wireless communication systems is evolving rapidly, making it difficult to build experimentation platforms that meet the hardware requirements of new standards. The bandwidth of current systems ranges from 160 MHz for IEEE 802.11ac/ax to 2 GHz for Millimeter-Wave (mm-wave) IEEE 802.11ad/ay, and they support up to 8 spatial MIMO streams. Mobile 5G and beyond systems have a similarly diverse set of requirements.To address this, we propose a highly configurable wireless platform that meets such… Show more

“…The transmitter implements a loopback memory that feeds the DACs with the I/Q symbols to be transmitted, which are loaded from an external processor. To enable AoD estimation (Section IV-B2), we implement a real-time antenna reconfiguration mechanism through General Purpose Input/Output (GPIO) pulses [42] that allows to sweep through different BPs while transmitting a packet. This feature is important when implementing the in-packet training functionality through TRN training sequences appended to communication packets [44].…”

“…M-Cube [54] reverse engineers the control path of COTS 60 GHz RF frontends to build mmWave multiarray and MIMO systems with up to 8 antenna arrays. The MI-MORPH platform [19] is an open source FPGA-based multiband system that supports real time operation. Several efforts exist to instrument COTS devices for mmWave experimentation.…”

“…We evaluate the performance of the adaptation methods on real over-the-air wireless experiments. We use a recent high-performance mmWave testbed [28], featuring a high-end FPGA board with 2 GHz of bandwidth per channel and 60 GHz SIVERS antennas [29]. This platform allows to transmit the custom constellations generated by the encoder and to store the data to be either trained by the MDN, or extracted for further performance analysis.…”
