MIMO Synchronization for USRP-2920/2921/2922/2930/2932 Devices

Last Modified: May 14, 2020

USRP devices support multiple-input and multiple-output (MIMO) synchronization from 2 × 2 to 8 × 8 antenna configurations.

You can combine multiple USRP devices to form a phase-coherent antenna array for transmission and reception in LabVIEW, LabVIEW NXG, and LabVIEW Communications System Design Suite.

A MIMO communication testbed requires all receive (RX) channels to act as a single receiver, and all transmit (TX) channels to act as a single transmitter. The MIMO testbed achieves synchronization by sharing a 10 MHz Reference Clock and a PPS timebase among the USRP devices.
