Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - In recent years, the innovation of multiple-input multiple-output (MIMO) has completely changed the face of wireless communication system. Especially, the concept of MIMO is evolved to fulfill the demand of multimedia services. However, challenges have risen to the system provider for maintaining the quality of service (QoS) and reliability of MIMO system. Additionally, very recently, cooperative communication has been proposed in order to face and deal with the shortcomings of MIMO system. In cooperative communication, the addition of relay between source and destination enhances the QoS and reliability of wireless system. The main purpose of this paper is to derive the closed form analytical expressions of symbol error rate (SER) of M-ary phase shift keying (MPSK) for MIMO decode-and forward (DF) relay system. Besides, SER derivation is based on moment generating function (MGF) of the overall system. In our case, we only deal with a downlink MIMO DF relay system. Here, we consider an nt-antenna at the source S, an nr-antenna at the relay R and an nd-antenna at the destination D, where the propagated signal from the source passes through keyhole and correlated channel.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Recently, high data rate communication system like long term evolution(LTE), ultra mobile broadband (UMB) and Wimax has gained popularity. But this high data rate communication is possible if the wireless system exhibits full rank MIMO channel.However, full rank MIMO channel is not possible if the channel is highly correlated and keyhole affected. In recent years, researchers have developed a new paradigm called cooperative communication in order to get rid of the limitations of MIMO techniques. In this paper, we have analyzed the performance of DF relay with keyhole and correlation effects in MIMO relay channel. Moreover, based on MGF approach we determine the closed form expression of average SER of the MIMO DF system. Based on our analysis, it is evident that cooperative scheme outperforms the keyhole affected non cooperative scheme.…
