The rapid growth of wireless communication services and the drastic reduction of the cost of electronic devices have led to a tremendous increase of wireless communication devices in today's wireless communication systems. While this trend has made the spectrum a stringent resource, it also makes it possible to develop new communication technologies that exploit the cooperation among the distributed wireless devices for more efficient spectrum resource utilization and higher transmission performance.

520 $a The rapid growth of wireless communication services and the drastic reduction of the cost of electronic devices have led to a tremendous increase of wireless communication devices in today's wireless communication systems. While this trend has made the spectrum a stringent resource, it also makes it possible to develop new communication technologies that exploit the cooperation among the distributed wireless devices for more efficient spectrum resource utilization and higher transmission performance.
520 $a This research focuses on modeling and evaluating various distributed wireless communication systems such as cognitive radio networks (CRNs) and multi-hop relaying networks. This objective is to improve the utilization of the limited spectrum resource and the performance of wireless systems using redundant devices in such dense and distributed communication systems. To address the problem, we conduct research in three different scales: the overall network scale, the multi-hop transmission scale, and the single-hop transmission scale. In each scale, we develop modeling techniques to analyze and optimize the spectrum sharing performance.
520 $a First, we develop a novel population dynamic model to study the spectrum utilization behavior of CRN secondary users. We integrate this population dynamic model with some typical CRN spectrum sensing and spectrum access strategies to analyze the spectrum utilization efficiency of the overall system. The analysis results are verified by simulations.
520 $a Then, we develop an innovative technique called "interference immune transmission" to resolve the challenging mutual interference problem in multi-hop relaying networks. This technique is studied in multi-hop relaying networks with both full-duplex and half-duplex decode-and-forward relays. We show the immunity immune transmission in multi-hop relaying can be realized with appropriate packet encoding and successive interference cancellation (SIC) techniques. This provides a fundamental way to resolve the challenging mutual interference problem in distributed wireless systems. Based on the interference immune transmission, we further develop an optimal relay selection algorithm to optimize the source-destination transmission rate. Interestingly, this wireless networking algorithm is similar to the well-known Dijkstra's algorithm of wired networks. Simulations are conducted to demonstrate the efficiency and the superior performance of the new algorithm.
520 $a Next, we study the challenging synchronization problem when using multiple wireless nodes to realize various cooperative communication strategies. It is difficult to synchronize the distributed transmitters in terms of carrier frequency and symbol timing. We develop a general transmission framework that can be used to implement many typical distributed cooperative transmission schemes with asynchronous transmitters, which means that the distributed transmitters do not need to realize perfect synchronization in carrier frequency and timing phase. Such perfect synchronization is costly in practice, and may even be impossible in many situations. With the asynchronous transmitters, we develop an algorithm for the receiver to resolve the asynchronism by suppressing both multiple carrier frequency offsets (CFOs) and multiple timing phase offsets (TPOs). Some typical distributed transmission schemes are studied and simulated. The results are demonstrated via testbed experiments.
520 $a Finally, we conclude this dissertation and point out some potential new research directions.
