A 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...
متن کاملA Novel Correlation Sum Method for Cognitive Radio Spectrum Sensing
Cognitive radio is a promising concept for coping with the spectrum scarcity in future generation wireless communication networks. This idea, including software-defined radio (SDR) as the enabling technology, was suggested by Mitola [1] to realize flexible and efficient usage of spectrum. An important component of cognitive radio is spectrum sensing to detect the presence or absence of a primar...
متن کاملSpectrum Sensing in Cognitive Radio
In modern wireless communications the spectrum is allocated to fixed licensed users and on the other side the number of wireless devices are increasing rapidly, that has lead to spectrum crunch. As the spectrum is precious it has to be utilized efficiently. The solution to mitigate this problem is Spectrum Sharing. One of the innovative approach to recognize and access the spectrum holes presen...
متن کاملSpectrum Sensing in Cognitive Radio
With the fast readying of latest wireless devices , the last decade has witnessed a growing demand for spectrum. However, the exploit spectrum assignment policy becomes a bottleneck for additional economical spectrum utilization, below that an excellent portion of the authorised spectrum is severely under-utilized. The inefficient usage of the restricted spectrum resources urges the spectrum re...
متن کاملA Hybrid Spectrum Sensing Method for Cognitive Sensor Networks
Existing spectrum sensing methods for cognitive radio do not consider the secondary network’s characteristics to obtain the frequency of spectrum sensing, i.e., the sensing period would be identical for secondary networks that have different traffic characteristics. In this paper, a hybrid sensing algorithm is proposed that finds the optimal sensing period based on both primary and secondary ne...
