Abstract: Adaptive modulation (AM) technique may make more promote in the execution of wireless communication systems through adaptively conformity transmitter parameters to fading channels; therefore, it has been taken as one of the key physical techniques. Error performance and throughput in MIMO wireless systems can be improved through the use of Adaptive Modulation. Adaptive modulation selection plays an important role in wireless communication since the wireless channel conditions vary progressively. This paper offers a general overview of the adaptive modulation scheme in wireless multiple-input multiple-output (MIMO) systems.

Keywords: Adaptive modulation, multiple input multiple-output (MIMO), Orthogonal frequency division multiplexing (OFDM), Bit error rate (BER).
