| Abstract(in English) | For achieving 2-layer smart spectrum access (SSA) which corresponds to feasible strategy of DSA, a development of spectrum awareness system (SAS) is required. We focus on a core signal processing in SAS, which is called signal area (SA) estimation. Simple-SA (S-SA) estimation has been developed as a method to find SA, which means occupying area by PU in time-frequency domain. One of the issues of S-SA estimation is that it increases false alarm. In this paper, we propose L-shaped false alarm removal (L-FAR). We analytically derive sub-optimum parameters for L-FAR based on constant false alarm rate (CFAR). Numerical evaluations show the sub-optimum solution can achieve competitive detection performance with the optimum solution. In addition, it is shown that the proposed method can achieve better detection performance compared to the other methods. |
