Verification of baseband data is an important step in the early development phase of LTE/LTE-A-ready products. Comparison values for baseband data (test vectors) from other sources can be very useful in order to verify the correct implementation of the standard. Option K81 for the R&S®SMx200A vector signal generator offers sample data for LTE at the bit level. The reference data enables users to test their own implementation of the specification. The LTE bit stream verification program shown here uses data generated by this option and offers a (bitwise) comparison with bit streams generated for an LTE downlink signal. Therefore it demonstrates, how easy the option R&S SMx-K81 can be integrated into the simulation and design process during the development of LTE/LTE-A handsets or base stations.
