Exploring NOMA for regular downlink and uplink frameworks, the utilization of NOMA is examined in downlink multiuser numerous information different yield (MIMO) frameworks, by proposing a novel MIMO-NOMA model with direct beamforming method. In this MIMO-NOMA framework, clients' get receiving wires are progressively assembled into various disjoint bunches, and inside each group a solitary bar is shared by all the get reception apparatuses those embrace NOMA. In this paper, the design of MIMONOMA system using Sensing Cognitive Radio Network is presented. A spectrum-sensing method is detects the free portions of the primary user’s spectrum and allocates it to secondary users. It derives from crosscorrelating an unknown signal with known ones to detect the unknown signal’s presence based on the basis of its Signal to Noise Ratio (SNR). Accordingly, an efficient scheme is developed here that is having better SNR vs Bit Error Rate (BER), SNR vs spectrum efficiency against a different MIMO-NOMA system.
