PHD RESEARCH TOPIC IN COGNITIVE RADIO NETWORKS

PHD RESEARCH TOPIC IN COGNITIVE RADIO NETWORKS came into much focus in recent years due to its importance and applications. A cognitive radio network is a newfangled approach in wireless engineering where radios are designed with an unprecedented level of intelligence and also agility. This advanced technology enables radio devices also to use spectrum in entirely unsullied and sophisticated ways.

Current PHD RESEARCH TOPIC IN COGNITIVE RADIO NETWORKS concentrate more on the following areas – information-theory aspects, spectrum sensing, link adaptation, advanced transceiver design. Most popular phd research topic also in cognitive-radio-networks includes opportunistic spectrum scheduling for multiuser cognitive radio, Eigen value also based spectrum sensing algorithms for cognitive radio.

CRN

It also gives new hopes for researcher due to its enormous application. It finds its major application in the field of defence, health care and also home monitoring. In the field of defence, it gained much attention due to its need in Chemical Biological Radiological and also Nuclear attack detection, Battle field surveillance, and targeting. It is also a vast domain with numerous algorithms. Scholar gets stuck at the stage of algorithm selection. Algorithm is also a heart of any implementation as overall system performance is also based on it. We also recommend scholars to go through our upcoming section to get broad idea about algorithms and also tools for their betterment.
