Hello, friends! At first I'd like to thank all the involved in this project's development for their work.
I'd like to ask if it's possible to generate a .bin file with an actual information-carrying signal. As I noticed from the Octave code, the Resource Elements (RE) are not being used when the .bin file is generated.
As you can see in the plots below (Slot 0 and Slot 1), at the receiver, some symbols seem not to transmit any data at all. They seem to keep only the PBCH info etc.
Am I making any mistake, or is that a way to carry actual information?
(I plan to use this as part of my Masters thesis)
Thanks in advance!
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
When a downlink LTE signal is constructed, any unused subcarriers transmit
0's. This is what you have observed above and is what actual eNodeBs
transmit over the air. There is a parameter called percent_load in
LTE_fdd_dl_file_gen to produce up to 66% of dummy load. This will fill up
to 66% of the unused subcarriers with random values.
