Hello all;

I have been able to capture an over-the-air LTE waveform and decoded both MIB and SIB1 from. I was able to convert the SIB1 bit to decimal but am unable to interpret my result. I have the information that the info content of SIB1 are:

PLMN identity,

Tracking area code,

Cell Id,

info on whether cell is barred or not

Intra Frequency cell reselection info,

CSG indication,

plus other ones(http://www.simpletechpost.com/2012/10/system-information-block-1.html).

the result i got after converting the SIB1 bit with matlab code:

for i=1:length(sib1{1,1})/8;

result(i) = bi2de(sib1{1,1}((1:4)+(i-1)*8,1)','left-msb');

end

disp(result);

is: 4    4   13    2    8    9    7    3    7   14    2    3    8    8    8    6    7    5    0    0    0    5 for frame 470

and

4    4   13    2    8    9    7    3    7   14    2    3    8    8    8    6    7    5    0    0    0    1 for fram 472.

Please can anyone help me with the interpretation of the values I got.

Thanks.
