PHYSICAL LAYER SECURITY IN UPLINK NOMA MULTI-ANTENNA SYSTEMS WITH RANDOMLY DISTRIBUTED EAVESDROPPERS

The physical layer security of uplink non-orthogonal multiple access (NOMA) is analyzed.A stochastic geometry approach is applied to analyze the coverage probability and effective secrecy throughput (EST) of the kth NOMA user, where a fixed or an adaptive transmission rate can be used.We consider a protected zone around the legitimate terminals to

AbstractResearch is a common feature in developed countries.Those quadruple topical ointment for dogs who dedicate themselves to this activity produce important tools for individual, community, and national development.However, developing countries suffer the opposite situation.In these nations, little investment is devoted to research, and they la
