Example Summary

LTE Toolbox can be used to generate standard-compliant baseband IQ downlink and uplink reference measurement channel (RMC) waveforms and downlink test model (E-TM) waveforms. These baseband waveforms can be modulated for RF transmission using SDR radio hardware such as the USRP®-based radio.

This example generates eight frames of a baseband RMC waveform using the LTE Toolbox which also includes the SIB1 message. Then, the example sends a continuous RF LTE waveform by looping transmission of these eight frames on the USRP® radio hardware for a specified time period.

If you have a second SDR platform, you can capture the transmitted waveform and decode the MIB and SIB1 messages using the companion exampleTwo-Antenna LTE Cell Search, MIB, and SIB1 Recovery Using USRP-Based SDR.
