Introduction
============

of the most undesired side-effects of wireless communications systems is interference. In wireless networks, where several nodes share the medium, interference is avoided with mechanisms that orthogonalize transmissions. The classic examples of such mechanisms include frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), and finally random access protocols like carrier sense multiple access with collision avoidance (CSMA/CA) [@bertsekas:data-networks]. However, besides channel orthogonilization, there have been several additional techniques throughout the years that attempt to combat this effect [@book:fundamental-wireless]. In more recent years, there is a trend to exploit interference in order to increase the network capacity [@dankberg97; @larsson05; @popovski06b; @zhang:physical-layer-nc; @katabi07a]. This technique is usually referred to as analog network coding (ANC) and we can first identify it in [@dankberg97], although not with this term. With ANC network capacity is increased since concurrent interfering transmissions are allowed. Nodes listen to transmissions and then forward the unprocessed analog signals to destination nodes where various algorithms for interference cancelation can be applied in
