Abstract (in Japanese) (See Japanese page) 
(in English) In dynamic spectrum access, statistical information of Primary User (PU) enables more reliable and efficient spectrum sharing.
We need accurate and low computational complexity spectrum measurement method to obtain PU's statistical information.
In this paper, we study on accurate signal detection method on time-frequency plane as a part of spectrum measurement technique.
Simple-Signal Area (S-SA) estimation is applied to the Fast Fourier Transform (FFT) based Energy Detection (ED) outputs to improve the signal detection performance and L-shaped false alarm removal can mitigate the destructive effect of false alarm.
More accurate spectrum measurement can be achieved by these methods, but the way to set parameters of L-shaped false alarm removal method has not been investigated.
It is difficult to calculate optimum parameters which attain maximum detection probability under certain false alarm probability.
In this paper, we analytically prove sub-optimum parameter setting method by ignoring S-SA.
We analytically derive false alarm probability and detection probability of L-shaped false alarm removal by considering the effect of correlation due to window function.
Numerical evaluations show that the validity of sub-optimum parameter compared to optimum parameter.
