Design and synthesize complex antenna elements and MIMO phased arrays and subarrays 2. Partition hybrid beamforming systems intelligently across RF and digital domains 3. Validate spatial signal processing algorithm concepts 4. Verify link-level designs using high-fidelity simulations 5. Evaluate the impacts of failed or imperfect elements and subarrays 6. Eliminate design problems before building hardware A fundamental goal of MATLAB and Simulink products for this application is to provide a direct path to expand the level of fidelity of the model over the many phases of project development. This includes tasks such as bringing measured data into the model for the antenna pattern and the propagation paths. It also includes expanding the level of fidelity of the RF chain by bringing in models of RF components in the context of multidomain simulation with Simulink. Note In the examples below we use Phased Array System Toolbox Antenna Toolbox RF Blockset RF Toolbox Communications System Toolbox and Global Optimization Toolbox to complete the associated workflows. Challenges Designing Massive MIMO Arrays for 5G As 5G standards continue to evolve the goals for higher data rates lower latency network access and more energy efficient implementations are clear. Higher data rates drive the need for greater bandwidth systems. The available bandwidth in the spectrum up through 6 GHz is not sufficient to satisfy these requirements. This has moved the target operating frequency bands up into the millimeter wave range for the next generation of wireless communication systems. Intelligent Array Design with Beamforming Smaller wavelengths at these higher frequency bands enable implementations with more antenna elements per system within small .
