    Hello,
    I tried to get AWGN BLER curve in 10MHz Bandwidth using LTE_sim_batch_BLER_curves.m,but the graph is strange.
    Some CQI graph didn’t appear and the other graph’s slope is not constant like the reference graph which included LTEAlinkDOC.pdf.
    Did I miss some parts? or too few the number of subframes?
    The parameter I changed below:
    – Bandwidth : 10MHz
    – Simulation type : SUSISO
    – PDCCH : false
    – # of subframes : 10000

    Sincerely, Hailey.

    Hi Hailey,

    thanks for this comment. The number of 10000 subframes is definitely sufficient, typically we use 5000 for this kind of simulation. Which version of the simulator are you using?

    Hi Stefan,
    I’m using a LTE-A Link Level Simulator v1.4.

    Sincerely,

    Dear Hailey,

    did you make sure, that the CQI feedback was turned off for this simulation?
