This study focuses on sea propagation environments and presents results on the characterization of the over-the-sea wideband mobile radio channel. Conducted measurements led to the development of path loss, log-distance models. The behavior of the power delay profile is also investigated in detail. In general, the mean excess delay and delay spread values(More)
Cognitive Radios (CR) have recently appeared as a solution to the spectrum scarcity problem, caused by static licensing policies. CRs can utilize spectral opportunities when and where Licensed Systems (LS) remain idle, operating in an overlay mode under the major restriction of not causing harmful interference to them. In this Paper, first, we investigate(More)
