A Multiband Frequency-hopping Communication System Based on Cognitive Radio
Shiping Yang · Telecommunication Engineering · 2012
To take full advantage of the spectrum sensing ability of cognitive radio(CR),a multiband frequency-hopping anti-jamming communication system is designed based on CR.Through dynamically controlling the generation of frequency-hopping(FH) sequence by CR unit,avoidance of the interference frequency spots is realized.In implementation,the cognitive information of high frequency band is reliably transmitted by the low frequency band,application data is transmitted by high frequency band,so the spectrum control and application traffic is isolated by different frequency band.
