My names is Amado.
I am student of master of science in the Mexico City. My investigation
is
about the physical layer of LTE. I revised the work of lte in gnuradio
wich
is excellent.


I have a question about IQ baseband samples of input.


¿What type of samples use?
¿How obtain the samples of input used in the test of LTE?


I hope you can help me with these questions

Hi Amado,

> ¿What type of samples use?
Mostly people use complex baseband samples. In C++ code in GR their
data type is gr_complex which is a wrapper for std::complex<float>.

> ¿How obtain the samples of input used in the test of LTE?
To get those samples you either generate them with a LTE transmitter
implementation or you record them. If you want to record them, there
are plenty of different options with different capabilites from USRPs
to Funcube Dongles to RTL-SDRs.

happy hacking
Johannes
