“… The number of selected relays: single [11]- [13]- [14]- [15] versus multiple relays [12]- [16] selection have been proposed for DF and AF relaying.  Pro-active versus reactive: In proactive mode [17], a specified relay selected prior to the source transmission participates in the cooperation, whereas in Reactive mode, relays that successfully decode the message take part in the cooperation.…”

Cognitive radio holds great promise as a research area nowadays. By increasing the spectral efficiency, it is applicable to various areas I. INTRODUCTIONSince the technology of wireless communication is quickly developing; heterogeneous wireless communication system must be adjusted in reduced frequency bandwidth. The efficiency of the conventional orthogonal spectral separation of heterogeneous system is not sufficient to sustain the unceasing growth of wireless device deploying exigency, making spectrum sharing amongst heterogeneous systems increasingly important. Two main challenges for the future of wireless systems are raised: the high data rate request of the growing number of users and the wireless spectrum availability. By reusing the underused licensed frequency bands, Cognitive Radio (CR) is presented as a new facet of telecommunication system to resolve the issue of spectrum availability. In such system, unlicensed wireless users (secondary users) are dynamically granted access to the licensed bands under the compulsion of tolerable interference to the Primary Users (PU). To facilitate the spectrum sharing among Secondary Users SUs and PUs, there are two existing techniques: The spectrum overlay and the spectrum underlay. In the first method, the SU shares some its power resources with the PU to give a relay-assisted transmission. Hence, the secondary network offsets the forced interference by the increase in the signal to interference plus noise ratio (SINR) of primary receivers. Thenceforth, the core idea of the overlay approach is to assign power and channel assets to the entire network, while using the requirements of PUs. To prevail over the spectral efficiency loss of one-way half duplex, [1] implements a two-way relaying.

“…8 and Fig. 9 present a comparison between the proposed relay selection technique and other approaches from the literature, namely the Max-Min technique analyzed in [8], the Max-Sum technique considered in [10], random selection over the relays in the pre-selected set K th , and random selection over all K relays. In Fig.…”

“…Thus a reliable transmission of information takes place from the source to destination by decoding the message whereas the incoming noise signal will not be amplified. Hence the maximum capacity and accurate symbol estimation is achieved by DF relay network [4][5][6][7][8].…”
