LTE Downlink System Level Simulator


Welcome to the TU Wien's Institute of Telecommunications'LTE simulator page. Here you will be able to get the last available version of the in-house developed, Matlab-based System Level LTE simulator.

The simulators are released under the terms of an academic, non-commercial use license. Please read the license agreement in case of doubt.

If you are experiencing problems with downloading or using the simulator please contact Josep Colom Ikuno or Martin Taranetz.


License


The LTE simulators are published under a non-commercial academic use license. Please make sure that you understand the terms and conditions of the license before you download any of the available software packages. Would you require a license different to a non-commercial academic one please contact Josep Colom Ikuno or Martin Taranetz.


Downlink System Level Simulator

The detailed license agreement for the LTE System Level simulator can be found here. Please read the license agreement carefully.


Software requirements


The LTE simulators are implemented in Matlab and require the following packages:

  • Matlab 7.8.0 (R2009a)
  • Statistics toolbox
  • Image Toolbox
  • Mapping Toolbox


Newer versions of the above packages should be supported, however, this was not tested.


Since the LTE simulators make use of the new Object-Oriented capabilities of Matlab (available since R2008a), the simulators will not run under older Matlab releases without extensive changes.


Please read THIS if you have problems/questions about the C code/MEX files included with the release.

 


Questions


For questions please check our forum, where you will be able to post your questions/comments/bug reports.


LTE Downlink System Level Simulator Package description


The main file of the LTE Downlink System Level Simulator is LTE_sim_main.m, though you may normally run the simulation through a batch file such as LTE_sim_launcher.m, which performs the following tasks:

  1. Loading a configuration file of choice.
  2. Executing the LTE_sim_main.m main simulation file.


The simulator allows for the following settings to be adjusted (please check the documentation for a complete list):

  • Number of TX and RX antennas.
  • Uplink delay
  • Number of frames to simulate
  • transmit and receive antenna numbers
  • network layout
  • channel model (macroscopic pathloss, shadow fading and microscale fading)
  • transmit mode (as defined by the standard)
  • scheduling algorithm


The released package also contains examples on how to use the simulator and plot its results.

 

LTE Downlink System Level Simulator functionality

 

The LTE System Level Simulation is still under development and as such, new features are planned to be added. For a complete list of all the functionalities, please refer to the documentation included with the simulator.
