Hi all, 

 

I got the follwing error when I run it for the fisrt time: 

 

Unrecognized property 'ReceiveArrayOrientation' for class 'nrCDLChannel'.

Error in construct_DeepMIMO_CDL_channel (line 38)
channel.ReceiveArrayOrientation = [ueArrayOrientation(1); (-1)*ueArrayOrientation(2); 0];
% the (-1) converts elevation to downtilt

Error in construct_DeepMIMO_channel_5G (line 23)
channel = construct_DeepMIMO_CDL_channel(txSize, txOrientation, rxSize, rxOrientation,
params_user, params);

Error in DeepMIMO_generator>generate_data (line 75)
[DeepMIMO_dataset{t}.user{user}.channel]=construct_DeepMIMO_channel_5G(params_inner.bsAntenna{t},
params_inner.bsOrientation{t}, params_inner.ueAntenna,
params_inner.ueOrientation(user, :), TX{t}.channel_params(user), params);

Error in DeepMIMO_generator (line 27)
DeepMIMO_dataset = generate_data(params, params_inner);

Error in DeepMIMO_Dataset_Generator (line 7)
[DeepMIMO_dataset, dataset_params] = DeepMIMO_generator(dataset_params);

 

I checked the class 'nrCDLChannel' in construct_deepmimo_CDl_channal.m and found that the 'ReceiveArrayOrientation' and 'TransmitArrayOrientation' were missing from the attributes.

 

Could you please help me to get out of this error?

Hi @Hao Li,

 

This is probably a MATLAB version problem. You need 2020B or later for running DeepMIMO 5GNR. Let me know if you have a newer MATLAB and still have the problem.

 

Regards,
Umut

Thank you for your reply!

 

The version I am using now is 2020B. In addition, the same problem will occur when I operate and set parameters according to the video in DeepMIMO 5G NR website( https://deepmimo.net/versions/5gnr/).

@Hao Li,

 

Thanks for bringing this to my attention. I've updated the version to support 2020b as well. Please re-download and try again.

Matlab has changed channel.TransmitAntennaArray.Orientation to channel.TransmitArrayOrientation in 2021a, and the DeepMIMO 5GNR was using the latter. Now, it is used based on the availability.

 

Thanks,

Umut
