The zero forcing (ZF), regularized ZF (RZF) and minimum mean squared error (MMSE) precoding schemes are considered, and the bit error rate (BER) is adopted as the performance metric of interest. Simulation results indicate that, an adequate BER performance is achieved by the proper control of the design parameters of RZF precoding. Moreover, a relationship between the number of users' antennas and the BS is observed, such that an adequate BER performance is achieved. 2019 IEEE.EnglishOctober University for Modern Sciences and Artsجامعة أكتوبر للعلوم الحديثة والآدابUniversity of Modern Sciences and ArtsMSA Universityminimum mean squared error (MMSE)Multiple input-multiple output (MIMO)regularized zero forcing (RZF)zero forcing (ZF).Bit error rateCodes (symbols)ErrorsFeedback controlMean square errorTelecommunication repeatersDesign parametersMinimum mean squared errorMulti user multiple input multiple outputsMulti-user MIMO systemsPerformance metricesPrecoding schemeTransmission performanceZero-forcingMIMO systemsConference Paperhttps://doi.org/10.1109/MWSCAS.2019.8885118
