    Dear Martin,

    Please I have two questions:

    1) How can I run channel estimator like MMSE in Vienna LTE-A Downlink Link Level Simulator v1.9?

    2) What is the purpose of using parallel in “LTE_sim_main_launcher_demo_parallel.m” ? and after run it I got the following error:

    Error using LTE_sim_main_launcher_demo_parallel (line 13)
    An UndefinedFunction error was thrown on the workers for ‘LTE_config’. This might be because the file containing ‘LTE_config’ is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for ‘parallel.Pool/addAttachedFiles’ for more details.

    Caused by:
    Undefined function or variable ‘LTE_config’.

    Kind regards

    Ali

    Dear Ali,

    are you really talking here about the Link Level Simulator? If so, to activate the MMSE channel estimator set LTE_params.UE_config.channel_estimation_method = ‘MMSE’ in the appropriate parameter file.

    However, I rather think that you are referring to the System Level Simulator, which does not support channel estimation at all. If so, please post your question in the system level simulator forum.

    Best,
    Stefan.
