Space Receive Diversity Techniques for Massive MIMO System Mobile communication systems became an attractive technology, and nowadays there is a high demand for wireless communication. To meet the ever increasing demands in cellular communications system with high data rate; Massive MIMO is a promising candidate technology for next generations of wireless communication systems. Hence the problem of severe attenuation in a multipath wireless environment makes it extremely difficult for the receiver at the base station to find out the optimum transmitted signal which leads to degrade the system performance SNR and Capacity. This paper gives a quantitative comparison of space receive diversity combining techniques which are SC, MRC and EGC for massive MIMO system over Rayleigh fading channel for massive MIMO system. The results indicate that the improvements of SNR and capacity is achieved by increasing number of receive antennas for three combining techniques. Lastly, the comparison made between three techniques explains that MRC is a better performance than SC and EGC to combat multipath fading for next generation of cellular communications.
