Abstract(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.
