Why can I not recover the MIB when I use the LTE Downlink Channel Example to Generate Waveform?

I am using the LTE Downlink Channel Estimation and Equalization example to generate a transmit waveform so I can recover the MIB (Master Information Block) using the Cell Search, MIB and SIB1 Recovery example. When I do so the decoding of the MIB fails, why is this?

The root cause of the issue is that the generated waveform does not include the MIB. The recommended way to generate a full LTE waveform is to use the "lteRMCDLTool" function, as shown in the "Cell Search, MIB, and SIB1 Recovery" example. Short of that, the user has to be careful to generate all required parts. For this case the waveform from the LTE Downlink example could be modified to include the MIB in the transmitted waveform.
