| dc.description | The need to attend more devices by ensuring higher data rate speeds with greater reliability and less energy consumption has forced the birth of a new generation of mobile communications, denominated fifth generation (5G), that is based, among other things, on the application of various technologies, among which the use of tens or hundreds of antennas in the receiver stands out and it is known as massive MIMO. This work evaluates the performance of a massive MIMO system that uses the ZF (Zero Forcing) detector and the MMSE (Minimum Square Mean Error) detector in channels with Rice-type fading considering M-QAM modulations. To this end, simulation algorithms were implemented in the Matlab software in order to generate bit error rate (BER) curves as function of the signal-to-noise ratio. Furthermore, these curves were obtained by modifying the system operating parameters such as the number of receiving antennas, the modulation order (M-QAM), and the power of the line-of-sight component (LOS) of the Rice channel. The results show that the MMSE detector achieves a lower BER than the ZF detector, this is because the MMSE detector reduces the mean square error between the transmitted bits and estimated bits by the receiver and makes it the best candidate in the presence of noise, this improvement is greater when the number of antennas in the receiver increases. In addition, it is evident that the use of 64-QAM improves the transmission rate, but the performance of the system degrades because this modulation is more susceptible to noise. | en |
