Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we explore potentials of cooperative communication at receivers' side in the downlink of wireless cellular networks for interference mitigation and signal enhancement. We investigate two regimes of latency and reliability of communication: one for providing high long-term average user rates for supporting a quality of service that is suitable for human visual and auditory perception, and the other for providing an ultrareliable low-latency machine-type wireless communication for streaming information in control applications. We consider three different models of cooperative communication. First, we study deploying a multi-antenna relay node that provides a nearby cell-edge user with extra dimensions over an out-of-band relaying link. We model this scenario by a Gaussian multiple-input multiple-output (MIMO) relay channel with correlated noise across relay and destination antennas, and analyze the capacity of this channel. This type of relay deployment is most effective when the number of receive antennas is small and the number of relay antennas is large enough. Second, we study deploying a multi-antenna half-duplex amplify-and-forward relay node that simultaneously provides multiple cell-edge users with extra dimensions. We show that the optimized relaying significantly improves the long-term average rates of cell-edge users, even after accounting for the extra bandwidth required for half-duplex relaying, provided that the relay is equipped with sufficiently many antennas. Third, we study cooperation among receivers for combating fading and mitigating interference for ultrareliable low-latency wireless communication. We consider multiple interfering broadcasts from controllers to their corresponding actuators. The recently-proposed Occupy CoW protocol efficiently exploits the spatial diversity of distributed receivers for combating deep fading. It consists of two consecutive phases: the broadcast phase and the cooperation phase. However, it avoids interference by orthogonalization; hence, its required bandwidth for achieving ultrareliability is not scalable in network size. We observe that full frequency reuse in the broadcast phase with successive interference cancellation notably improves the scalability of this protocol. We propose two schemes depending on whether interference cancellation or interference avoidance is implemented in the cooperation phase, and show that both outperform Occupy CoW, each in its own preference region.

Available in PDF, EPUB and Kindle. Book excerpt: Wireless communications have become a fundamental feature of any modern society. In particular, cellular networks are essential for societal welfare but the increasing demand for data traffic set enormous scientific challenges. Increasing the network capacity is closely related to the problem of interference mitigation. In this regard, network cooperation has been studied in recent years and several different techniques have been proposed. In the first part, different transmission techniques commonly referred to as Coordinated Multi-Point Transmission (CoMP), are studied under the effect of feedback quantization and delay, unequal pathloss and other-cell interference (OCI). An analytical framework is provided, which yields closed-form expressions to calculate the ergodic throughput and outage probabilities of Coordinated Beamforming (CBF) and Joint Transmission (JT). The results indicate the optimal configuration for a system using CoMP and provide guidelines and answers to key questions, such as how many transmitters to coordinate, how many antennas to use, how many users to serve, which SNR regime is more convenient, whether to apply CBF or prefer a more complex JT, etc. Second, a new coordination technique at the receiver side is proposed to obtain sum-rate gains by means of Successive Interference Cancellation (SIC). The conditions that guarantee network capacity gains by means of SIC at the receiver are provided. To take advantage of these conditions, network coordination is needed to adapt the rates to be properly decoded at the different users involved. This technique is named Cooperative SIC and is shown to provide significant throughput gains for cell-edge users.

Book excerpt: Active remote sensing is the principal tool used to study and to predict short- and long-term changes in the environment of Earth - the atmosphere, the oceans and the land surfaces - as well as the near space environment of Earth. All of these measurements are essential to understanding terrestrial weather, climate change, space weather hazards, and threats from asteroids. Active remote sensing measurements are of inestimable benefit to society, as we pursue the development of a technological civilization that is economically viable, and seek to maintain the quality of our life. A Strategy for Active Remote Sensing Amid Increased Demand for Spectrum describes the threats, both current and future, to the effective use of the electromagnetic spectrum required for active remote sensing. This report offers specific recommendations for protecting and making effective use of the spectrum required for active remote sensing.

Download or read book Low overhead Cooperation to Mitigate Interference in Wireless Networks written by Steven Wayne Peters and published by . This book was released on 2013 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless cellular networks, which serve a large area by geographically partitioning users, suffer from interference from adjacent cells transmitting in the same frequency band. This interference can theoretically be completely mitigated via transceiver cooperation in both the uplink and downlink. Optimally, base stations serving the users can utilize high-capacity backbones. to jointly transmit and receive all the data in the network across all the base stations. In reality, the backbone connecting the base stations is of finite capacity, limiting joint processing to localized clusters. Even with joint processing on a small scale, the overhead involved in sharing data between multiple base stations is large and time-sensitive. Other forms of cooperation have been shown to require less overhead while exhibiting much of the performance benefit from interference mitigation. One particular strategy, called interference alignment (IA), has been shown to exploit all the spatial degrees of freedom in the channel provided data cannot be shared among base stations. Interference alignment was developed for the multi-user interference channel to exploit independent channel observations when all of the links in the network have high signal-to-noise ratio, and assumes all the nodes utilizing the physical resources are participating in the cooperative protocol. When some or all of the links are at moderate signal-to-noise ratio, or when there are non-cooperating users, IA is suboptimal. In this dissertation, I take three approaches to addressing the drawbacks of IA. First, I develop cooperative transmission strategies that outperform IA in various operationg regimes, including at low-to-moderate SNR and in the presence of non-cooperating users. These strategies have the same complexity and overhead as IA. I then develop algorithms for network partitioning by directly considering the overhead of cooperative strategies. Partitioning balances the capacity gains of cooperation with the overhead required to achieve them. Finally, I develop the shared relaying model, which is equivalent to the interference channel but with a single multi-antenna relay mediating communications between transceivers. The shared relay requires less overhead and cooperation than interference alignment but requires added infrastructure. It is shown to outperform conventional relaying strategies in cellular networks with a fixed number of total relay antennas.
