Abstract
In previous chapters, different cooperative relaying schemes have been introduced under the basic setting where relays are each equipped with a single antenna and transmit over a single-carrier channel. However, cooperative diversity can actually be exploited on top of many other transmission technologies. In particular, the use of cooperation in orthogonal frequency-division multiplexing (OFDM) and multiple-input multiple-output (MIMO) systems have received much attention in recent years due to its importance in current and next generation wireless systems. In this chapter, we first introduce a basic cooperative OFDM system and describe an efficient power and subcarrier allocation algorithm for this system. In this chapter, we first introduce a basic cooperative OFDM system and describe an efficient power and subcarrier allocation algorithm for this system.
