Abstract

A cognitive radio (CR) access technique is a promising solution for the dynamic spectrum resource usage. This paper presented a CR testbed system employing a wideband multi-resolution spectrum sensing (MRSS) technique. Analog implementation of the MRSS block offers wideband, low-power, and real-time operation. The MRSS experiments were performed using the developed CR testbed system. The experiment results showed that the MRSS technique detected wideband 100-MHz spectrum in a sparse or a precise manner without any increase of hardware burden. Moreover, this MRSS technique detected a variety of sophisticated signal formats adopted in the current and emerging wireless standards - IS-95, WCDMA, GSM, EDGE, Wi-Fi (IEEE802.Ha/b/g), ATSC, DVB, etc.
