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 in 3GPP Evolved Universal Terrestrial Radio Access (E-UTRA). This paper offers a general overview of the adaptive modulation scheme in wireless multiple-input multiple-output (MIMO) systems. Study a set of properties by which adaptive modulation systems are evaluated, and then apply this valuation method to survey a number of existing systems, also, discuss modulation schemes and channel modeling in detail since it is utilized in most current system or solutions, as well survey some MIMO models which are included in adaptive modulation activities in order to reproduce and corresponding MIMO system ratings. Comprehensive execution comparisons including, BER analysis, average spectral efficiency (ASE), modulation schemes, and channel model are presented.

Index Terms—Adaptive modulation, MIMO, orthogonal frequency division multiplexing (OFDM), imperfect channel state information (CSI), bit error rate (BER), average spectral efficiency.
