LTE NB-IOT MIB encoding / decoding

I am currently using LTE toolbox, specifically, for NB-IOT simulations. in the NB-IOT downlink example code, the lteBCH function is used to encode the NB-MIB (34 bits). Can lteBCHdecode also be used to decode the NB-IOT MIB? So far, i have not had any luck using lteBCHdecode for decoding the NB-MIB.

Hi Ron,

MATLAB R2019b onwards lteBCHDecode function supports the NB-IoT 34 bits MIB decoding. Your problem should be solved if you work on the latest release.

BTW, if you are working on NB-IoT downlink simulations, for NPBCH encoding and decoding, there are functions lteNPBCH and lteNPBCHDecode released in R2019b MATLAB version. To see an example of how to use them, see "NB-IoT Cell Search and MIB Recovery" example.
