[Openlte-discuss] LTE signal captures

[Thomas T. <tt...@vt...>]

Hi All,

I posted some captured data of the local LTE downlink signal. There
are two tarballs of three captures of 1 second each; the 'mat' archive
contains raw .mat files generated by the test equipment at 12.5 Msps,
while the 'bin' file has resampled and scaled packed 8-bit integer
data at 30.72 Msps for OpenLTE use.

Samples are captured from a Tektronix RSA6100 spectrum analyzer at
12.5 Msps. The 751 MHz signal can be seen in the following screenshot.

I can decode the MIB, but not consistently. The SIB does not decode.
Any thoughts?
