Hybrid Beamforming for Massive MIMO Phased Array Systems
This white paper illustrates a process to design hybrid beamforming in massive MIMO antenna arrays for 5G, using features available with MATLAB® and Simulink®.
Taking a 64 x 64 element, 66 GHz millimeter wave (mmWave) design as an example, we show a strategy to model antenna arrays and partition beamforming operations between the digital and RF domains, including:
Specifying an array and visualizing the geometry, 2D and 3D directivity, and grating lobes
Importing antenna patterns to increase model fidelity
Mitigating the effects of array element imperfections, element and subarray failures, and mutual coupling
Designing array architectures and generating RF phase shifts and digital complex weights
Measuring performance of link-level designs using high-fidelity, RF/digital multidomain simulations
Modeling multi-user beamforming scenarios
Assessing tradeoffs between performance, power dissipation, and implementation complexity
