How can I send user data with lte_fdd_dl_transmit.m?

[Leonardo]

Dear all,

My task is to change the application lte_fdd_dl_transmit.m such that, instead of sending only synchronization, reference and control signals (PSS, SSS, RS, etc), it also sends information bits (on PDSCH?).

I have been looking at the code lte_fdd_dl_transmit.m and I believe I should modify the map_pdsch function or include something outside the if in line 247:

% PDCCH & PDSCH
if(mod(frame_num,2) == 0 && subfr_num == 5)

I think I could pass QAM symbols in variable mod_vec where it is empty.

My question is:
- Is it the right way or another (easier) alternatives are available?

Thank you in advance.
