FD-MIMO Multi-channel, Reference Solution

Multiple-input/multiple-output (MIMO) technology can provide communications networks with increased data throughput and high data integrity through path diversity, spatial multiplexing and beamsteering/ beamforming techniques. The improved antenna gain overcomes path loss, enabling higher data rates per hertz compared with an isotropic signal at the same power. Full Dimension MIMO (FD-MIMO) is already under development, progressing toward standardization by the 3rd Generation Partnership Project (3GPP) for LTE-Advanced Pro. The application of beamforming in both azimuth and elevation enables a base station to steer its signal to a specific user. The use of antenna arrays for beamforming is well established in radar and communications applications. The relative amplitude and phase of the multiple transmit signals are dynamically adjusted at each antenna element to create the desired beam pattern. Different base station architectures apply the beamforming algorithm in different ways. For example, relative phase and amplitude differential could be applied at different stages of the transmit chain, either at the RF, at baseband, or a combination of both. The signal conditioning can be accomplished in different domains – analog, digital or a hybrid of the two. Operational performance and end user experience will be dependent on the system working to design limits. This requires characterization of signal quality in 3D space. As a starting position, it will be necessary to characterize relative amplitude, phase and delay variations across all transmit elements.

MIMO Beamforming Design and Verification Challenges

As MIMO extends to full-dimension azimuth and elevation beam steering with 64, 128 and more antenna elements, both practical and comprehensive measurement techniques are needed to verify designs and qualify products.

Solutions for MIMO Characterization and Verification

Keysight Technologies is uniquely positioned to help you improve your time-to-insight while keeping your total cost of test under control. Our MIMO test solutions are highly scalable with comprehensive measurement capability based on 3GPP specifications. With the introduction of beamforming, and as the number of antenna elements increases, verification of base-station performance becomes increasingly complex. Multi-channel measurement solutions based on traditional bench-top instrumentation are no longer practical or efficient, and new methods are required to ensure reliable and repeatable characterization right to the measurement plane. Keysight solutions scale to the large port-count required for MIMO antenna arrays, incorporating novel techniques to improve measurement accuracy and repeatability.
