MMWCAS-DSP-EVM: Post Processing Cascade Data

Hi all,

I am setting up the use case for a Cascade setup as instructed in the mmWave Studio Cascade guide.

I have the setup successfully capturing data using the DSP and RF -EVM boards.
But am now struggling with visualisation of the data using Matlabs.

• Created the Environment in Windows - success
• Run "add.paths.m" in Matlabs - success
• Calibration (skipped for now, awaiting delivery of a corner reflector) but am using (or trying to use) the default example "calibrateResults_high"

and now my problems:


(1) Once the calibration data is collected, go to the .\main\cascade folder in matlab and update the “dataFolder_calib_data” in “cascade_MIMO_antennaCalib.m” to point to calibration data folder.

I'm not entirely sure what to update in this file so I have updated the following fields, in the hopes this is correct and to point it towards the default calibration example in \main\cascade\input

input_path = strcat(pro_path,'\main\cascade\input\');

dataFolder_calib_data = '\main\cascade\input\';

and this is the output within Matlab when i try to run the "cascade_MIMO_antennaCalib.m" :

>> run cascade_MIMO_antennaCalib.m

dataPlatform =

'TDA2'

Error using parameter_file_gen_antennaCalib_json
Unknown parameter file or too many chirpProfiles_*.jason file!!

Error in cascade_MIMO_antennaCalib (line 62)
parameter_file_gen_antennaCalib_json(dataFolder_calib_data, pathGenParaFile, dataPlatform);

Error in run (line 91)
evalin('caller', strcat(script, ';'));

(2) Post Processing

• Collect the raw adc data for the actual scenario using the lua script provided for MIMO.
• Update the first line of the \input\testList.txt file to point to the Captured Data folder (as shown below).
• Update the second line of the \input\testList.txt file to point to the corresponding calibration vector generated from the calibration step
• Update the third line for algorithm parameter tuning if needed; the default values are in \paramGen\module_param.m
  

testList.txt

- line 1: C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\PostProc\Tom_Cascade

- line 2: .\input\calibrateResults_high.mat (left default, but my understanding is that this should be fine?)

- line 3: .\paramGen\module_param.m (left default but the assumption is the same as the above?)

and the output of this when i try to run the "cascade_MIMO_signalProcessing.m" file in Matlab is:

>> run cascade_MIMO_signalProcessing.m

dataPlatform =

'TDA2'

paramFile= C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\PostProc\Tom_CascadeTom_Cascade.mmwave.json
Error using loadjson

Any help would be greatly appreciated

Thanks, Tom.
