Question for NB-IoT Waveform Generation

Referring to below link, LTE system toolbox supports NB-IoT downlink waveform generation. Is NB-IoT "uplink" waveform generation also supported? https://www.mathworks.com/examples/lte-system/mw/lte_product-NPDSCHBlockErrorRateExample-nb-iot-npdsch-block-error-rate-simulation-and-waveform-generation

NB-IoT uplink is not explicitly supported in LTE System Toolbox R2017b. Can I ask what your particular application is?

Cheers,

NB-IoT PA testing, and uplink waveforms are needed as input signal to PA.

Hi Middle, thanks for the info. There may be suitable waveforms that could be create out of existing LTE System Toolbox functionality. It would depend on the required veracity of the signal content for the PA testing. Probably best to contact your local MathWorks application engineering support for further help.

Hello again,

R2018b of the LTE Toolbox now adds NB-IoT uplink support, as well as LTE-M MTC/eMTC BL/CE modelling. For more info, see the full Toolbox release notes:

The two uplink NB-IoT related examples are:

Hi, I am using Matlab 2018 but I need 2019 , but my laptop is not supporting, what should I do ? I need this new NB-IOT results

What aspect of your laptop is not supported by R2019a ?
