Chapter 6Cooperative SMTs

Cooperative communications create collaboration through distributed transmission/processing by allowing different nodes in a wireless network to share resources. The information for each user is sent out not only by the user but also by other collaborating users. This includes a family of configurations in which the information can be shared among transmitters and relayed to reach final destination in order to improve the systems overall capacity and coverage [209, 216230]. As such, cooperative technologies have made their way toward wireless standards, such as IEEE 802.16 (WiMAX) [231] and long‐term evolution (LTE) [232] and have been incorporated into many modern wireless applications, such as cognitive radio and secret communications.

Driven by the several advantages of space modulation techniques (SMTs) and cooperative communication technologies, cooperative SMTs have been extensively investigated in the past few years. Reported results promise significant enhancements in spectral efficiency and network coverage [98, 206, 233244].

In this chapter, cooperative SMTs are studied and analyzed. In particular, amplify and forward (AF), decode and forward (DF), and two‐way relaying (2WR) will be considered.

6.1 Amplify and Forward (AF) Relaying

In cooperative AF relaying, a source (S) and destination (D) nodes are communicating, and multiple or single AF relays participate in the communication protocol as illustrated in Figure 6.1.

Figure 6.1 AF cooperative SMT ...
