The non-orthogonal multiple access (NOMA) technique developed for 5G next generation communication technology which has some promises such as providing high spectral efficiency has been the key point of researches lately. A new structure has been obtained by integrating the heterogeneous NOMA technique with the multiple input multiple output (MIMO) technique, which provides high data rate. Providing transmission with more than one antenna in this structure causes problems such as high cost, system complexity and excessive power consumption. Antenna selection has been the subject of this article in order to eliminate or minimize the problem. As a result of the literature studies on this subject, it has been noticed that the max- max-max and max-min-max antenna selection algorithms are frequently used. However, only the speed performances of the algorithms were examined and other parameters were not evaluated in the studies. Here BER, outage probability, capacity analyzes of algorithms are discussed and simulation studies are carried out using MATLAB/Simulink program. From the results obtained, it was concluded that the BER values of the user who is close to the base station are better than the user who is far away, and as the distance to the base station decreases, the BER values improve, the capacity increases and the outage probability decreases.
