This paper presents an analytical study on the outage performance of cognitive decode-and-
forward (DF) two-way relaying networks with underlay spectrum sharing. The bidirectional …

Cooperative networks have developed as a useful technique that can achieve the same
advantage as multi-input and multi-output (MIMO) wireless systems such as spatial diversity …

Recently, cooperative relay networks have emerged as an attractive communications
technique that can generate a new form of spatial diversity which is known as cooperative …
