description: In modern communication networks, relays play a vital role in cooperative communication. Different relaying strategies like decode and forward, amplify and forward, and quantize and forward have been proposed for the relay networks. The use of relaying in communication networks improves spectral efficiency. For instance, in a two-way relay channel, two users can exchange data by using a transmission medium simultaneously. When these relay networks are used with advanced technologies like unmanned aerial vehicle (UAV) and mm-Wave networks, new limitations are faced like line of sight obstructions. Such networks become more susceptible to blockages leading to intermittent connectivity. However, the capacity of the intermittent two-way relay channel has not been studied in the literature. In this thesis, we calculate capacity bounds and achievable rates for the intermittent two-way relay channel. We classify our system model into three different cases depending on the knowledge of the channel state at different nodes in the networks. We consider an ideal case where channel states are available at all the nodes in the network and calculate the cut-set bound and achievable rates of different relaying schemes. We then extend our results to practical cases where limited channel state information is available. We compare the bounds and achievable rates, and discuss the capabilities and limitations of different relaying schemes in each of the three cases.
