要約(英語): This paper discusses the primary signal detection technique for sharing the spectrum of an ultra-wideband radio system with other radio systems. A detect and avoid technique is required to not affect the interference frequency band allowed under the regulations of some countries. In many interference avoidance techniques, it is necessary to detect the emission of the primary signals and their occupied bands. In this paper, the received primary signal is correlated with the sub-band pulses, averaged and compared with the threshold value to detect the emission of the primary signal. To obtain better detection performance, the sub-band pulse width is derived. The interfering frequency band is also estimated from the ratio of correlation values that are obtained from two consecutive sub-band pulses. The detection error rate, false alarm rate and root mean square error of frequency are evaluated to show the effectiveness of the proposed primary signal detection technique.
