A Comparative study on NOMA oriented Backscatter Communication

The recent attraction of intentness from the industry as well as academia are derived by the shoot up in 5G communication technologies, consumer electronics, healthcare, cloud computing enabled big data analytics and agriculture. There are various types of challenges in these fields such as security challenges, design challenges, deployment challenges etc. One of the considerable wide challenge is the limited lifetime of network. Reason of limited lifetime are massive devices those are being activated by the finite capacities batteries. Backscatter communications (BackCom), a technique based on the phenomena of low power and low complexity of network is a hopeful technique to tackle this challenge. BackCom technique depend on inert reflection and amendment in an incident radio frequency wave. Also the exploration of non-orthogonal multiple access (NOMA) technique became very useful in fifth and beyond fifth generation of networks to increase its capacity. The combination of the two techniques, NOMA and BackCom, gives new prospects in multi cell NOMA networks in terms of connectivity. It leads several new challenges in condensed wireless network. The significant improvements of the combination of NOMA and BackCom are mentioned in comparison with the standard technique of orthogonal multiple access (OMA) ambient BackCom.
