    I am currently using Matlab R2014a and latest version of Vienna LTE-A Uplink Link Level Simulator. When i open LTE_UL_quickest.m and click RUN directly, a lot of errors occur as shown in the followings :

    Starting parallel pool (parpool) using the ‘local’ profile … connected to 2 workers.
    *************** SNR = 03.64 db, value 4 of 12 ***************
    *************** SNR = 21.82 db, value 8 of 12 ***************
    Error using LTE_UL_channel_estimator (line 26)
    Reference to non-existent field ‘channel_est_frequency_smoothing’.

    Hello,

    are you using version 1.5 of the LTE-A uplink simulator?

    Hi,

    thank you for your feedback. Unfortunately you are right, when running the LTE_UL_quick_test.m, some variable names inside scripts are wrong.

    greetings

    Hi,

    for future reference, this bug was already fixed within Release 1.5. From now on, you should not encounter this problem anymore.

    greetings
    Stefan
