Abstract (in Japanese) (See Japanese page) 
(in English) The problem with conventional cyclostationarity-based feature detection
is that the detection probability of weak signals degrades if multiple signals with different received-power levels are captured simultaneously.
Multiple signal identification has been studied in order to solve such a problem. The multiple signal identification method in which the appropriate notches suppress the effects of other signals was proposed and evaluated by using computer simulations and basic experiments. In this paper, the multiple signal identification method is evaluated based on realistic testbed experiments. In order to evaluate the method in a realistic environment as a field test, a spatial channel emulator and an antenna of a mock terminal are applied to the test bed. The results reveal the effectiveness of the proposed method in realistic spectrum sharing scenarios in which the multiple signals with different received power are received simulaneously.
