Subject: | SIB1 messages decoder using GNU Radio |
Date: | Sat, 28 Mar 2020 01:32:59 +0000 |
Hello GNU Radio team,
I have a project I'm working on which is about Obtaining SIB1 messages from captured DL IQ data been taken from CPRI link prop, a Complex Input.
Kindly to advise on how to decode SIB1 messages using the GNU Radio, using this complex DL IQ as input data.
For example, If the CPRI link has 8 AxC “antenna carriers” for two bands, B1 has 4 AxC, and the other second band has the remaining 4 AxCs.==> I'm interested in decoding the SIB1 messages from
this captured DL IQ data so I can know which AxC is belong to which band.
How to achieve this in GNU Radio? Thanks in advance. Samples from the first band: SegmentLength = 308736,SegmentLength = 308736,SegmentLength = 308736,SegmentLength = 308736 -1480-796j,58-52j,1347+896j,-2546+811j -130+303j,1571-1090j,1371+2119j,-1653-1267j 253+1436j,971-1526j,464+1796j,-1375-817j -1138+1343j,-471-145j,23-147j,-1869+1310j -1320-536j,-1214+788j,377-720j,-794+1740j Samples from the second band: SegmentLength = 308736,SegmentLength = 308736,SegmentLength = 308736,SegmentLength = 308736 33-397j,-550-15j,1924+1456j,1275-1671j -103+36j,-386-142j,-96+1107j,1639-1555j 76+175j,188+59j,-1172-381j,634-109j 120+118j,529+383j,-1110-1353j,-849+916j Kind Regards, Hassan Al Shekha.
