Spectrum Agile Radio: Detecting Spectrum Opportunities
The opening up of the unlicensed bands for commercial use has been a tremendous success. Wireless communications in computing, mobile, medical and consumer electronics market segments have grown rapidly in the past few years. Due to this success, radio resources in the unlicensed bands are progressively becoming scarce. Recently, the Spectrum Policy Task Force (SPTF) within the FCC has recommen...
متن کاملAdaptive Signal Detection in Auto-Regressive Interference with Gaussian Spectrum
A detector for the case of a radar target with known Doppler and unknown complex amplitude in complex Gaussian noise with unknown parameters has been derived. The detector assumes that the noise is an Auto-Regressive (AR) process with Gaussian autocorrelation function which is a suitable model for ground clutter in most scenarios involving airborne radars. The detector estimates the unknown...
متن کاملto Radio Spectrum
Congested military spectrum means that next generation communication systems will have to achieve much greater spectral efficiency than their predecessors. In this paper, we consider various examples of approaches that increase the overall spectral efficiency of a communication system. Advanced signal processing techniques provide significant increases in throughput, replacing legacy VHF voice ...
متن کاملSpectrum Sharing Method for Cognitive Radio in TV White Spaces: Enhancing Spectrum Sensing and Geolocation Database
This paper proposes a system called Wireless Link based on Global Communication Channel (WLGCC) to enhance the spectrum sharing between digital broadcasting (DB) services and the cognitive radio (CR) system in the licensed band of 470-790 MHz. The WLGCC aims to enhance the spectrum sensing and geolocation database (GLD) spectrum sharing methods in the CR system. Spectrum sensing can be enhanced...
متن کاملA New Spectrum Sensing Method for Cognitive Radio
Cognitive radio has been proposed as a possible solution to improve spectrum utilization via opportunistic spectrum sharing that will be done by autonomous detection of vacant bands in the radio spectrum. Spectrum sensing is the very task upon which the entire operation of cognitive radio rests. In this paper a new spectrum sensing method for cognitive radio systems based on cyclic autocorrelat...
