But now i would wanted to study how to receive the LTE downlink signals from mobile companies. I was recommended to use 30.72 MHz as sampling rate instead of 1.96 MHz used in the code of the link above. My question is : Why do i have to use this sampling rate (if it is correct)? And which equation i must use to get the sampling rate of a signal? I guess it should be a little higher than the signal bandwidth.
Thank you for the help in advance,
