Abstract : In a short while wireless communication become widely used and one of the main transmission systems at all kind, new generations shows up with new techniques, Massive MIMO antenna is what we focus on in this paper and specifically, the downlink of linearly pre-coding multi-user of Multi-input Multi-output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system that has been studied using The Regular Zero Forcing (RZF) to adequate the Bit Error Rate (BER), and in addition, the Minimum Mean
Keywords : RZF, BER, Orthogonal Frequency Division Multiplexing, The Regular Zero Forcing, Bit Error Rate
