Abstract

This paper presents a 2 × 2 millimeter wave (mm-wave) multiple-input-multiple-output (MIMO) testbed that operated surrounding 30 GHz. The link assessment of the system operating at 26.25 GHz between the transmitting and receiving ends was carried out for on a test bench with a short communication distance. A user-programmable, reconfigurable and real-time signal processing field-programmable gate arrays (FPGAs)-based software defined radio (SDR) system was employed as part of the testbed to validate the system-level performance for a downlink time division long-term evolution (TD-LTE) duplex scheme. Constellation diagram for quadrature phase shift keying (QPSK) digital modulation were acquired in which the testbed was operating at 30 GHz. The testbed could be employed for the development of signal test, communication algorithm and measurement metrology for 5G communications.
