Resumen
This paper presents a comparison of the efficiency and computational complexity of successive interference cancellation (SIC) and ordered successive interference cancellation (OSIC) detectors in massive MIMO systems using QAM modulation. The challenge for the signal detectors of these systems is that as the number of antennas increases the detector complexity also increases. Therefore, so is important to have an efficient low-complexity detector. These four detectors are evaluated in a system of 16 antennas in transmission, 64, 100 and 200 antennas in reception using 4 QAM, 16 QAM, and 64QAM modulators, to evaluate the efficiency and computational complexity of each detector by increasing the number of receiving antennas and with different QAM modulation. With the result that increasing the number of antennas and decreasing the modulation index improves the performance of the system, since the higher the gain, the lower the probability of signal loss. The evaluation of the detectors in these systems shows that the OSIC detectors present better performance but have greater computational complexity.
