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. |
