Abstract (in Japanese) (See Japanese page) 
(in English) Dynamic Spectrum Access (DSA) can be enhanced by statistical information of actual spectrum usage. The information is available by wide-band spectrum measurement. To improve the measurement accuracy, the authors had developed measurement parameter design scheme based on prior information about layout of signals in time-frequency plane. In this paper, measurement parameter for Welch FFT-energy detector is decided by optimization problem about detection accuracy with time resolution constraint. There is a difficulty that detection probability analysis has very large computation amount. Our proposed method, quasi-optimizer, using only mean and variance of test statistic on energy detector for brevity, can reduce computation complexity.
Therefore, analysis of mean and variance of test statistic is shown.
Numerical evaluation shows validity of the method.
