  • Massive MIMO is the presently most compelling sub-6 GHz bodily-layer generation for destiny Wi-Fi. The 5G structures are characterized via high transmission data quotes, 1Gbps and above, so huge bandwidth transmission is anticipated. The maximum critical goals inside the design of 5G Wi-Fi systems are to address the extreme inter symbol interference (ISI) as a result of the excessive statistics prices, and to make use of the available bandwidth in spectrally efficient manner. To aid the time various QoS in multiuser surroundings for 5G structures (Massive -MIMO) is the robust candidate. Channel fading is distinctive at different sub companies, this feature may be exploited for allocating the subcarriers to the users in line with the immediately channel nation facts (CSI). A very excessive facts rate is most desired for the usage of multimedia and Internet, so on this paper surveys the overall performance of Shannon Hartley theorem and Eigen matrix set of rules which allocates the channels to customers for high facts prices inside the uplink and downlink transmission of MC-CDMA structures. This paper particularly analyzes the BER performance beneath Rayleigh fading channel conditions of MC-CDMA in presence of AWGN (Additive White Gaussian Noise) the usage of QPSK modulation for distinct number of subcarrier, special quantity of customers using MATLAB program
