Overview of MIMO OFDM Simulation Matlab Project: OFDM Simulator can be simply defined as the Simulator which can combine dissimilar signals at the same time using diverse Frequencies. The operation of this simulator is similar to a Music system where several tones play in coordination with a chord at the same time.

WHERE IS OFDM SIMULATOR USED?

Let’s understand some major uses of OFDM Simulator

• It is widely used in the latest wireless digital data communication.

MAJOR MODULES AND THEIR USAGE

Below are a few major modules of the MIMO OFDM Simulation Matlab Project. Scholars can use any of the below modules or can use a combination of Modules to implement their projects under our complete support and guidance
