Dear Engineers
I can’t use read_ADC_bin_TDA2_separateFiles.m (path: ’C:\Users\Administrator\Desktop\work\data\adc_data’) to read the radar collection data, please give your suggestions.
code shows as below

When I use this function as :Rxchain = read_ADC_bin_TDA2_separateFiles('C:\Users\Administrator\Desktop\work\data\adc_data',1,256,128,8, 4, 4),the System error is:
Where is my problems or How to deal with this question?
Thanks again for your kind help!

Shine:
请检查一下单引号,逗号是不是英文的?路径用反斜杠试试。
,
Yihong Luo:
单引号和逗号都是英文格式的,路径改成反斜杠后也是同样的错误。

Chris Meng:
你好,
在mmwave studio 3.0.0.14里,有MIMO 的Matlab例程,包括配置,采集,数据处理,建设你参考一下。
