Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This article derives the packet error probability (PEP) of different relay selection techniques for cognitive radio networks (CRN). The power of secondary source and relays is adaptive to not cause high interference to primary receiver \(P_R\). Secondary nodes harvest energy from radio frequency signals to be able to communicate. CRN with secondary nodes transmitting with adaptive power was already studied in the literature. However, in all previous studies, secondary nodes use their own batteries to transmit. The main motivation of our paper is to study CRN with energy harvesting and adaptive transmit power (ATP). We derive new expressions of PEP and throughput for CRN with energy harvesting and ATP. Our results are valid for opportunistic relaying, partial relay selection and reactive relay selection. Our main contribution is to optimize harvesting duration to maximize the system throughput.
