Ambient Backscatter Communication in 5G

Cognitive Radios (CR) is to overcome spectrum scarcity and it provides functions in the form of sensing, decision taking, sharing and mobility of the spectrum. One of the critical issue in wireless networks is energy efficiency due to technological limitations on energy requirements. A new form of communication known as ambient backscatter communication (ABC), allows the devices to transmit information by reflecting the existing signals. This paper has investigated the energy efficiency parameters w.r.t. normalized transmission period in ABC harvest then transmit (HTT) based cognitive radio networks with respect to 5G requirements.
