Natural spectral lines

"Our proposed algorithms exhibit better performance in terms of convergence speed and solution quality with saving rates reaching over 98.93% and 46.60%, respectively," the team reports. It allows secondary, users to operate in the holes between the spread of frequencies reserved by law for the primary users. The system could cope with 1024 sub-carriers. The approach could be useful in wireless healthcare applications, multimedia, and elsewhere.
