This paper deals with the design of low complexity dynamic spectrum access (DSA) scheme for Cognitive Radios (CRs) to search the vacant band of tunable bandwidth, Bh. Such DSA scheme with tunable Bh is very critical for CRs considering the coexistence of multiple communication standards in wideband input signal with channel bandwidths ranging from 25 kHz to 20 MHz and users expectations of seamless...
The problem addressed in this paper is the test for presence of any telecommunication signal within a given frequency band, which is of great importance for cognitive radios. Since a telecommunication signal is well modeled as cyclostationary, we transform this problem to the one of testing for presence of the cylostationary property over a range of cyclic frequencies and we propose a constant false...
