With the development of mobile, robust, ubiquitous, reliable and instantaneous communication being a driving and enabling factor of an information centric economy, the understanding, mitigation and exploitation of interference in networks must be seen as a centrally important task. Thus, when handled properly, "mixing" of data in networks becomes a useful tool of operation rather than the nuisance as which it has been treated traditionally. In fact, an exciting insight into the operation of networks is that it may be beneficial, in terms of an overall throughput, to actively create and manage interference. The latter type of approach tries to solve the joint detection and estimation problem of several data streams that share a common medium. In this chapter, two-way relaying networks using Physical-Layer Net- work Coding (PLNC) are considered with. It investigates centralized and decentralized methods to avoid and handle interference as well as approaches that resolve interference constructively. This chapter deals with the proper selection of waveforms for multi-carrier systems in the Two-Way-Relay Channel (TWRC) using PLNC and addresses Generalized Frequency Division Multiplexing (GFDM) compared to Orthogonal Frequency Division Multi-plexing (OFDM) under practical constraints.
This book offers means to handle interference as a central problem of operating wireless networks.
