Patent number: 7860197Abstract: Spectrum-sensing algorithms and methods may be provided for use in cognitive radios and other applications. The spectrum-sensing algorithms and methods may include receiving an input spectrum having a plurality of channels, performing a coarse scan of the plurality of channels of the input spectrum to determine one or more occupied candidate channels and vacant candidate channels, where the coarse scan is associated with a first resolution bandwidth and a first frequency sweep increment, performing a fine scan of the occupied candidate channels and the vacant candidate channels to determine actually occupied channels and actually vacant channels, where the fine scan is associated with a second resolution bandwidth and a second frequency sweep increment, and storing an indication of the actually occupied channels and the actually vacant channels.Type: GrantFiled: September 17, 2007Date of Patent: December 28, 2010Assignee: Samsung Electro-MechanicsInventors: Youngsik Hur, Chang-Ho Lee, Jeongsuk Lee, Kihong Kim, Haksun Kim

Patent number: 7528751Abstract: Embodiments of the invention may provide for a long delay generator for the spectrum sensing of cognitive radio systems. The long delay generator may include an Analog-to-Digital Converter (ADC), memory element, and Digital-to-Analog Converter (DAC). The memory element may utilize shift register bank or Random-Access Memory (RAM) cells. The long delay generator may provide for a selectable delay by digitizing the received signal, delaying the received signal in the digital domain, and reconstructing the delayed signal as an analog. The analog delayed signal may then be compared or otherwise correlated with the original input signal using an analog auto-correlation technique to determine whether a meaningful signal type has been identified or otherwise detected.Type: GrantFiled: July 16, 2007Date of Patent: May 5, 2009Assignees: Samsung Electro-Mechanics, Georgia Tech Research CorporationInventors: Jongmin Park, Taejoong Song, Kyutae Lim, Chang-Ho Lee, Jeongsuk Lee, Kihong Kim, Seongsoo Lee, Haksun Kim, Joy Laskar
