In today’s mobile communications technologies can be used less and less to serve the growing needs of the users. Smart phones and their applications, appearing on the market, require higher bandwidth and lower latency. That is why a new generation of wireless transmission standard was developed, called Long Term Evolution (LTE), which has also been available in Hungary’s nundination from 2012.

Therefore, I chose to present this technology and investigate the associated test facilities. These include the use of multiple antennas at both the transmitter’s and receiver’s side. (MIMO: multiple-input and multiple-output). Another possibility is that the base station serves more than one user with MIMO. Schedulers to select these users appear to be a good test criterion as well.

In my thesis I present the basics of LTE technology and MIMO solutions. I implement a simulation environment that is suitable for the MIMO transmission and multi-user MIMO schedulers testing. At the end of my work I run simulations with different settings and analyze the results.
