The bandwidth  gets expensive owing to shortage of frequencies. For  efficient utilization of spectrum, we need to sniff  the spectrum to determine whether it is used by  primary user or not. The term cognitive radio refers  to the adoption of radio parameters using the sensed  information of the spectrum. There are three major  categories of spectrum sensing techniques;  transmitter detection, receiver detection and  interference temperature detection.  This book presents a survey of techniques suggested  in the literature for spectrum sensing with a  performance analysis of transmitter-based detection  techniques. A Fuzzy logic based technique for primary user  detection has also been proposed. In comparison with  transmitter detection techniques purposed technique  provides good results under low SNR values.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844321128\"\u003e\u003ch3\u003eSpectrum Sensing\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844321128","offer_id":39495950270557,"sku":"9783844321128","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/441d0048-e180-49a3-9be5-e98dc0f04683.jpg?v=1759296085","url":"https:\/\/shop.autorenwelt.de\/en\/products\/spectrum-sensing-in-cognitive-radio-networks-von-waleed-ejaz-und-mehak-basharat","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
