Outage Probability and Ergodic Capacity Analysis of MIMO-NOMA Heterogeneous Network for 5G System
Based on the orthogonal multiple access (OMA) paradigm, multiple access techniques are now used in wireless networks. The capacity of OMA for orthogonal resources, which is already constrained, will be exceeded in the coming years by the demand for a ...
