Abstract :In recent years, there has been a vast amount of research on cooperative diversity due to its potential capacity increase. Almost all of the research has been based on linear modulation formats such as phase-shift keying insert ignore into journalissuearticles values(PSK); or quadrature amplitude modulation insert ignore into journalissuearticles values(QAM);. On the other hand, continuous phase modulation insert ignore into journalissuearticles values(CPM); promises impressive advantages relative to linear modulations for wireless communication systems. In this paper, a cooperative diversity scheme with space-time coded insert ignore into journalissuearticles values(STC); CPM is introduced. Both amplify-and-forward insert ignore into journalissuearticles values(AF); and decode-and-forward insert ignore into journalissuearticles values(DF); modes were considered for cooperation. Simulation results showed that the proposed system is very suitable for wireless fading channels, since it provides diversity gain and utilizes the advantages of CPM.
