During the past years, there has been a quickly rising interest in radio access teCh- nologies for providing mobile as well as nomadic and fixed services for voice, video, and data. The difference in design, implementation, and use between telecom and datacom teChnologies is also getting more blurred. One example is cellular teChnologies from the telecom world being used for broadband data and wireless LAN from the datacom world being used for voice over IP.

Optical communication teChnology has been extensively developed over the last 50 years, since the proposed idea by Kao and Hockham [1]. However, only during the last 15 years have the concepts of communication foundation, that is, the modulation and demodulation teChniques, been applied. This is pos- sible due to processing signals using real and imaginary components in the baseband in the digital domain. The baseband signals can be recovered from the optical passband region using polarization and phase diversity teCh- niques, as well as teChnology that was developed in the mid-1980s.

LTE-Advanced becomes a truly global standard for 4G cellular communications. Relay, as one of the key teChnologies of LTE-Advanced, can significantly extend the coverage, and improve the system throughput. LTE-A standards and teCh- nologies were described in several recent books where the limited pages for relay feature prevent the detailed explanations of the teChnology. In this book, we tried to provide an in-depth description of LTE-A relay development. More specifically, significant portions are spent on relay channel modeling and potential teChnologies during the study item phase of the development, although some of those teCh- nologies, such as Type 2 cooperative relay, multi-hop relay, relay with backhaul of carrier aggregation, were not standardized in Release 10 LTE.

In the past few decades, a teChnological revolution has occurred that has changed the way we live in dramatic ways. This teChnological revolution is the result of the emergence and evolution of a wide variety of new wireless networking teCh- nologies. Now people using these teChnologies are able to access the network and control many applications at will with their handheld devices anywhere, anytime. Although these teChnologies have made a long lasting impact in the revolution, it has also opened up various challenging issues which are yet to be resolved to make them more efficient and cost-effective.
