An Outage Probability in Cooperative MIMO under (Alamouti, Orthogonal and Quasi Orthogonal STBC) Slow Fading Channel

Abstract

Slow fading channel is one of the most important channels, which appears widely in a cellular mobile system. It has several problems such as bad effects of fading, which causes an attenuation to the signal. This paper presents a new scheme in cooperative communication system under slow fading channel to enhance and increase the quality of communication systems performance. This new scheme is called a cooperative multiple input�multiple output Antenna. The main idea of this scheme depends on transmitting multi copy of message via two paths. It�s performance has been compared with MIMO technique in term of outage probability. The results show that the negative effects of fading are mitigated and the outage probability and diversity gain are enhanced. Furthermore, the reliability in communication system under slow fading channel is improved.
