Performance comparison of modulation techniques for underlay cognitive radio transceivers
2013
International Conference on Communication and Electronics System Design
Preserved Fulltext
In this paper, we present a quantitative comparison of two agile modulation techniques employed by cognitive radio transceivers operating in a dynamic spectrum access (DSA) network. ...
One of the modulation techniques is single carrier frequency division multiple access (SC-FDMA). ...
The choice of physical layer transmission technique is a very important design decision when implementing a cognitive radio. ...
