'Modeling and Simulation of MIMO RF Receiver Including Beamforming'
5 views (last 30 days)
In the example model 'Modeling and Simulation of MIMO RF Receiver Including Beamforming' I was learning the model by running the simulation. For my analysis I changed the frequency F0 from 5GHz to 28 GHz. I changed the frequency tones in the RF configuration block accordingly like shown in image or even if I select automatically select fundamental tones
and when I run I recieve this error message ''An error occurred while running the simulation and the simulation was terminated
- ['simrfV2_mimo_antenna/Receiver/RF_Receiver/Configuration/Solver Configuration']: Delay history is too long. Decrease the delay time or increase the time step. ''
Can someone tell me where and what to change?

Have you tried changing the delay time or the time step as the error message suggests? This documentation will provide you more info on what parameters to change: https://www.mathworks.com/help/simrf/ref/configuration.html
If it doesn't solve the issue, please share the model with the modifications that you're working on so I can take a look. I tried to reproduce the issue with the frequency F0 as 28 GHz and the fundamental tones and harmonies that you used, but I wasn't getting the same error.
However, I did get that error "Delay history is too long. Decrease the delay time or increase the time step. ''" when F0 was set at the default value.
