Then, you can use any ASN.1 SIB decoder to read the message. This site http://www.marben-products.com/asn.1/services/decoder-asn1-lte.html is a good example.
If you don't have a pair of USRP, you can also test the demo by writing the samples to a file and then reading them:
From the eNodeB, type
```
lte/phy/examples/pdsch_enodeb -o [output_file] -c [cell_id] [-h for more commands]
```
From the UE, type
```
lte/phy/examples/pdsch_ue -i [input_file] -c [cell_id] [-h for more commands]
